TCS LATEST PAPER 34
Hi all,shubham this side and i will share my personal experience on TCS campus drive.I m in final year of my MCA.I assure you that cracking TCS written and interview is easy,u just need to focus on qualifying written.TCS came to our campus on 10th september 2011.Same procedure top 5 from every branch and ppl who are having throughout 75% are directly called for interview.
Written test was based on that 70 odd patterns.Touchstone software was used.You will be given 80min to do 35 questions.it is an online test.For written jst prepare last year papers of TCS from fresher world and that will be more than enough,no need to study nething else for written.remember there is 1/3rd negative marking so attempt questions about which u r sure.try to attempt around 25-30 questions.
In my college around 100 students appeared for written and they selected only 43 and i was among 43 luckily.They were saying NIT KURUKSHETRA is grade A college in there list so they increased cutoff because of which only 43 students are selected.
After written test they had small presentation and then interview.Dont get nervous in interview,keep urself calm and be confident and u will get through.They had 2 rounds:
1.)technical+MR
2.)HR
My technical round is as follows
I went inside,wished interviewer
I:-Ok Shubham u did ur graduation from AGRA?
me:-no sir i completed my graduation from lucknow bt my college was affiliated to GARA university.
I:-Ok,tel me what is OOPS
me:-told
I:-write a program to show function overriding
me:-did
I:-asked me to explain the program
me:-did
I:-how is function overloading different from function overriding?
me:explained
I:-ok good.tell me some latest technologies in IT market(by latest he means which came 2-3 months back)
me:-sry sir
I:-so u dnt read ne tech magzine and didnot visit tecnical websites
me:-sir i do visit technical websites bt not on regular basis.
I:-ok,Why TCS?
me:-I said,work pressure is less there and BLA BLA BLA
I:-Shubham I am working in TCS for last 10 years and there is so much of work pressure and i need to work 11 hours a day
me:-ok sir,there is no problem in working 11 hours a day bt my boss must not be standing on my head for every work.
I:-ok,so u r saying u can work 24*7?
me:-sir i can,bt there must be balance in professional and social life.
I:-ok shubham thanku.
me:-thanku sir.
my interview just went for around 10 min.remember dont get nervous,look towards interviewer at the time of interview and in technical they jusy ask basics so be clear in ur basics of C,C++,database.
next round was HR i was called off just after 15 min i completed my technical,remember techical interviewer gives feedback of every student to HR and whose feedback is good those students are called immediately for HR.
HR was very friendly of age around 25-28.
HR:-are u tensed
me:-yes mam a bit as it is my 1st interview.
HR:-calm down,take ur time.
then she asked my introduction and around 20-25 min she just bullied me about my weakness which i told that i sleep a lot during my free time.so be prepared well with ur introduction.they just check ur communication and confident.always smile in front of HR(short and sweet smile).show that u r confident about what u r speaking.In HR just keep on answering what HR is asking and be logical in ur answers.be ready with real life examples of ur strenghts,weakness and achievements.
At last she asked about relocations,i said i have no problem.
after all this i waited around 4-5 hours for results and at last they said they will mail result to TPO.next day around 9PM result came and i was among 62 selected from 143(including 35 toppers).
BEST OF LUCK TO ALL TCS ASPIRANTS.WILL MEET U AT TCS
for any queries message me at 9541747808.no calls plz only msgs.i will help u in every possible manner.

TCS LATEST PAPER 33
1.Online Aptitude test
2.Technical interview
3.Managerial interview
4.HR interview
The paper pattern for aptitude was 35 questions in 80 min.
NOTE:PATTERN OF TCS PAPER HAS BEEN CHANGED NOW NO VERBAL,REASONING.IT HAS ONLY APTITUDE.
Here are some of the questions which were there in my exams.
Question1: There is a toy train that can make 10 musical sounds. It makes 2 musical sounds after being defective. What is the probability that same musical sound would be produced 5 times consecutively? (1 of )?
Answer: 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32
32 will be the answer. (My friends got similar question with "3 times consecutively"; for that the answer would be 8)
Question2: A research lab in Chennai requires 100 mice and 75 sterilized cages for a certain set of laboratory experiments. To identify the mice, the lab has prepared labels with numbers 1 to 100, by combining tags numbered 0 to 9. The SPCA requires that the tags be made of toxin-free material and that the temperature of the cages be maintained at 27 degree Celsius. Also, not more than 2 mice can be caged together and each cage must be at least 2 sq.ft in area. The 5 experiments to be conducted by lab are to be thoroughly documented and performed only after a round of approval by authorities. The approval procedure takes around 48 hours. How many times the tag is numbered '4' used by the lab in numbering these mice?
a)9 b)19 c)20 d)21
Question3: A sheet of paper has statements numbered from 1 to 70. For all values of n from 1 to 70. Statement n says ' At least n of the statements on this sheet are false. ‘Which statements are true and which are false?
a)The even numbered statements are true and the odd numbered are false.
b)The odd numbered statements are true and the even numbered are false.
c)The first 35 statements are true and the last 35 are false.
d)The first 35 statements are false and the last 35 are false.
Solution: Suppose the first 35 statements are true!
Statement 1: At least 1 statement is false [TRUE]
Statement 2: At least 2 statements are false [TRUE]
...
Statement 35: At least 35 statements are false [TRUE]
--------------------------------------------------------------------
Statement 36: At least 36 statements are false [FALSE]
..
Statement 40: At least 40 statements are false [FALSE]
--------------------------------------------------------------------
AT LEAST puts the minimum tag or the floor tag on the statements
So, if the first 35 statements are true and the rest are false, everything fits into place!
Question4: In the reading room of a library, there are23 reading spots. Each reading spot consists of a round table with 9 chairs placed around it.

a)8 b)7 c)6 d)8
Question16: Alok and Bhanu play the following coins in a circle game. 99 coins are arranged in a circle with each coin touching two other coins. Two of the coins are special and the rest are ordinary. Alok starts and the players take turns removing an ordinary coin of their choice from the circle and bringing the other coins closer until they again form a (smaller) circle. The goal is to bring the special coins adjacent to each other and the first player to do so wins the game. Initially the special coins are separated by two ordinary coins O1 and O2. Which of the following is true?
In order to win, Alok should remove O1 on his first turn.
In order to win, Alok should remove one of the coins different from O1 and O2 on his first turn.
In order to win, Alok should remove O2 on his first turn.
Alok has no winning strategy.
Solution: Between special coins there are two gaps.
first of 2 coin
second of 95 coin
if anuj goes with 2 coin gap he will lose as it is even
if anuj goes with 95 coin gap he will win as it is odd & last turn will be his
Question17: Susan made a block with small cubes of 8 cubic cm volume to make a block 3 small cube long, 9 small cubes wide and 5 small cubes deep. She realizes that she has used more small cubes than she really needed. She realized that she could have glued a fewer number of cubes together to lock like a block with same dimensions, if it were made hollow. What is the minimum number of cubes that she needs to make the block?
a) 114 b) 135 c) 21 d) 71
Solution: The total volume (in terms of number of cubes) of the solid = 3*9*5 = 135
The total volume (in terms of number of cubes) of the hollow = (3-2)*(9-2)*(5-2)
= 21
so number of cubes required = 135-21 = 114
Question18: In the year 2002, Britain was reported to have had 4.3m closed – circuit television (CCTV) cameras – one for every 14 people in the country. This scrutiny is supposed to deter and detect crime. In one criminal case, the police interrogate two suspects.

a) 11 b) 6 c) 10 d) 5
Question19: Given a collection of 36 points P in the plane and a point equidistant from all points in P, which of the following are necessarily true?
The points in P lie on a circle.
The distance between any pair of points in P is larger than the distance between X and a point in P
a) A and B b) neither A nor B c) B only d) A only
Solution: A only. B is not possible because line joining any two points in P becomes a chord which is always less than the radius (line joining X and any point in P) of circle
Question20: Spores of a fungus, called late blight, grow and spread infection rapidly. These pathogens were responsible for the Irish potato famine of the mid-19th century. These seem to have attacked the tomato crops in England this year. The tomato crops have reduced and the price of the crop has risen up.

She can make out the difference between a hat and a glove. She takes out an item out of the closet only if she is sure that if it is a glove. How many gloves must she take out to make sure she has a pair of each color?
a)50 b) 8 c) 60 d) 42
Solution: in the first case the lady takes up 32 red color
then he takes up 24 y (cause he should take up pair)
then he takes up 1y+1blue
then 2blue(cause to make sure he has a pair of each color in hand)
32+24+2+2=60
Question23: Francois Pachet, a researcher at Sony Computer Science laboratories is also a jazz musician. He decided to build a robot able to improvise like a pro.

b) There is more coffee in the first tumbler than water in the second tumbler
c) There is as much coffee in the first tumbler as there is water in the second tumbler
d) None of the statements holds true.
Question26: There are two water tanks A and B, A is much smaller than B. While water fills at the rate of one liter every hour in A, it gets filled up like 10, 20, 40, 80, 160... In tank B. (At the end of first hour, B has 10 liters’, second hour it has 20, and so on). If tank B is 1/32 filled after 21 hours, what is the total duration required to fill it completely?
a) 26 hrs b) 25 hrs c) 5 hrs d) 27 hrs
Question27: Middle – earth is a fictional land inhabited by Hobbits, Elves, dwarves and men. The Hobbits and the Elves are peaceful creatures who prefer slow, silent lives and appreciate nature and art. The dwarves and the men engage in physical games. The game is as follows. A tournol is one where out of the two teams that play a match, the one that loses get eliminated. The matches are played in different rounds where in every round, half of the teams get eliminated from the tournament. If there are 8 rounds played in a knock-out tournol how many matches were played?
a) 257 b) 256 c) 72 d) 255
Solution: let no. of teams be x
after first round there will be x/2 teams remaining
after second round there will be (x/2)1/2=x/4 teams remaining
similarly
after eight round there will be (x/2^8) teams will be remaining
but after eight round only the winner team is remaining
therefore x/256=1;
x=256;
next
in eighth round 2 teams will be competing
so there will be 1 match
in 7th round 4 teams =2 matches
similarly
in first round 256 teams=128 matches
what we require is
total no. of matches played=1+2+4+8+16+32+64=128=255
Question28: On planet korba, a solar blast has melted the ice caps on its equator. 9 years after the ice melts, tiny planetoids called echina start growing on the rocks. Echina grows in the form of circle, and the relationship between the diameter of this circle and the age of echina is given by the formula
d = 4*√ (t-9) for t ≥ 9
Where d represents the diameter in mm and t is number of years since the solar blast. Jagan recorded the radius of some echina at a particular spot as 7mm. How many years back did the solar blast occur?
a) 17 b) 21.25 c) 12.25 d) 12.06
Question29: Rearrange the following letters to make a word and choose the category in which it Ms RAPETEKA
a) Bird b) Vegetable c) City d) Fruit
Question30: Alok is attending a workshop “How to do more with less” and today's theme is Working with fewer digits. The speakers discuss how a lot of miraculous mathematics can be achieved if mankind (as well as womankind) had only worked with fewer digits. The problem posed at the end of the workshop is-
How many four digit numbers can be formed using the digits 1, 2, 3, 4 , 5 ( but with repetition) that are divisible by 4?
Can you help Alok find the answer?
a) 100 b) 125 c) 75 d) 85
Question31: A car manufacturer produces only red and blue models which come out of the final testing area completely at random. What are the odds that 5 consecutive cars of the same color will come through the test area at any one time?
a) 1 in 16 b) 1 in 125 c)1 in 32 d) 1 in 25
Solution: Prob of red = 1/2
Prob of blue = 1/2
Prob of 5consecutive colors is (1/2)^5
But there are two cases, cars are either all red or all blue so
Ans will be 2*(1/32)^5 ie 1 in 16
Question32: One day Alice meets pal and byte in fairyland. She knows that pal lies on Mondays, Tuesdays and Wednesdays and tells the truth on the other days of the week byte, on the other hand, lies on Thursdays, Fridays and Saturdays, but tells the truth on the other days of the week. Now they make the following statements to Alice – pal. Yesterday was one of those days when I lie byte. Yesterday was one of those days when I lie too. What day is it?
a) Thursday b) Tuesday c) Monday d) Sunday
Explanation:
On Thursday, Pal say truth i.e. yesterday (Wednesday) was one of those days when I lie. It’s true.
On the other hand, On Thursday, Byte lie i.e. yesterday (Wednesday) was one of those days when I lie too. It’s a lie. So both satisfied. Hence it’s Thursday.
Question33: Six friends decide to share a big cake. Since all of them like the cake, they begin quarreling who gets to first cut and have a piece of the cake. One friend suggests that they have a blindfold friend choose from well shuffled set of cards numbered one to six. You check and find that this method works as it should simulate a fair throw of a die. You check by performing multiple simultaneous trials of picking the cards blindfold and throwing a die. You note that the number shown by the method of picking up a card and throwing a real world die, sums to a number between 2 and 12. Which total would be likely to appear more often – 8, 9 or 10?
a) 8 b) All are equally likely c) 9 d) 10
Question34: A number when divided by D leaves a remainder of 8 and when divided by 3D leaves a remainder of 21. What is the remainder left, when twice the number is divided by 3D?
a) 13 b) cannot be determined c) 3 d) 42
Solution: suppose the no. is a
a = Dx +8 …….(1)
a = 3Dy + 21 …….(2)
So from 1 & 2 we get
D(x-3y) = 13
13 is prime so x-3y has to be 1
let x = 4 and y = 1
We get a = 60
2a = 120
So 120 when divided by 3D = 39
we get remainder as 3
So answer is 3
Question35: A toy train produces at least 10 different tunes when it moves around a circular toy track of radius 5 meters at 10 meters per minute. However, the toy train is defective and it now produces only two different tunes at random. What are the odds that the toy train produces 4 consecutive music tunes of the same type?
a)1 in 16 b) 1 in 4 c) 1 in 8
Solution: It can produce sound A , prob = 1/2 * 1/2 * 1/2 * 1/2 = 1/16
or sound B , prob = 1/16 (with the same logic)
So, probability of consecutive sound = 1/16 + 1/16 = 1/8
After the aptitude the results were announced at 8:00 pm in the night.I was very worried about my selection.I had done 30 questions but still I was worried about the cut off score.There is negative marking also.The cut off score is generally around 19,20.So if you do around 25 questions you are on the safer side.Just go through the previous papers.I was lucky to be the one among who were selected but then was the tension of next three rounds.
It was on the next day.So I would suggest for the technical interview read according to the branch in which you are as tcs people don’t ask you anything beyond it.And don’t try to fool them as they have google.com in front of them to verify us.So if you don’t know simply tell them.If you have some achievements in btech tell them about it.They are interested.My waiting time for interview started at 9 in morning.I was called at 9:30 at night.So after a long time duration I was not even a single bit tired due to my craze for TCS.There were 14 panels for the interview.I got panel 7 which constituted of the seniormost official of tcs and one another tcs person.They were famous for getting into the depth of technicality.That was the point when I was thinking that my bad luck wont leave me..But happened next was …I entered the room..
Me:May I come in Sir?
1st person:Yah sure please come in.
(I entered and wished them)
Me:Good evening Sir.
1st:Very good evening Harshita.So have a seat.
So how was the day Harshita?
Me:It was very nice sir.
1st :U had to wait for a long time.Wasn’t it tiring?
Me:Absolutely not sir.I enjoyed waiting.
1st:Ok harshita so tell me about urself..
Me:Told..about various presentations..prize at IIT,roorkee and proposal at IIT,Kharagpur..etc…
1st:Ok then tell me about the present research you are doing..
Me:Told about my research.
1st:If u are doing so much research so do you want to carry on it in future?
Me:Told

(After one hour I was sent for the HR interview)
10 ppl wer called at the same time.We wer made to stand in a semicircle.Then in 30 seconds wer asked to divide into team of two.So five teams wer formed.Then the HR told us abt software lyf cycle.The five departments and asked every team to take one an dxplain y dey opted for it.We took the enhancement department and justified it.
At about 12 am night results wer announced and I was the lucky one to be der..So just dying to write the line wich I read in all the placement papers..Finally got the chance…..
2.Technical interview
3.Managerial interview
4.HR interview
The paper pattern for aptitude was 35 questions in 80 min.
NOTE:PATTERN OF TCS PAPER HAS BEEN CHANGED NOW NO VERBAL,REASONING.IT HAS ONLY APTITUDE.
Here are some of the questions which were there in my exams.
Question1: There is a toy train that can make 10 musical sounds. It makes 2 musical sounds after being defective. What is the probability that same musical sound would be produced 5 times consecutively? (1 of )?
Answer: 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/32
32 will be the answer. (My friends got similar question with "3 times consecutively"; for that the answer would be 8)
Question2: A research lab in Chennai requires 100 mice and 75 sterilized cages for a certain set of laboratory experiments. To identify the mice, the lab has prepared labels with numbers 1 to 100, by combining tags numbered 0 to 9. The SPCA requires that the tags be made of toxin-free material and that the temperature of the cages be maintained at 27 degree Celsius. Also, not more than 2 mice can be caged together and each cage must be at least 2 sq.ft in area. The 5 experiments to be conducted by lab are to be thoroughly documented and performed only after a round of approval by authorities. The approval procedure takes around 48 hours. How many times the tag is numbered '4' used by the lab in numbering these mice?
a)9 b)19 c)20 d)21
Question3: A sheet of paper has statements numbered from 1 to 70. For all values of n from 1 to 70. Statement n says ' At least n of the statements on this sheet are false. ‘Which statements are true and which are false?
a)The even numbered statements are true and the odd numbered are false.
b)The odd numbered statements are true and the even numbered are false.
c)The first 35 statements are true and the last 35 are false.
d)The first 35 statements are false and the last 35 are false.
Solution: Suppose the first 35 statements are true!
Statement 1: At least 1 statement is false [TRUE]
Statement 2: At least 2 statements are false [TRUE]
...
Statement 35: At least 35 statements are false [TRUE]
--------------------------------------------------------------------
Statement 36: At least 36 statements are false [FALSE]
..
Statement 40: At least 40 statements are false [FALSE]
--------------------------------------------------------------------
AT LEAST puts the minimum tag or the floor tag on the statements
So, if the first 35 statements are true and the rest are false, everything fits into place!

Question16: Alok and Bhanu play the following coins in a circle game. 99 coins are arranged in a circle with each coin touching two other coins. Two of the coins are special and the rest are ordinary. Alok starts and the players take turns removing an ordinary coin of their choice from the circle and bringing the other coins closer until they again form a (smaller) circle. The goal is to bring the special coins adjacent to each other and the first player to do so wins the game. Initially the special coins are separated by two ordinary coins O1 and O2. Which of the following is true?
In order to win, Alok should remove O1 on his first turn.
In order to win, Alok should remove one of the coins different from O1 and O2 on his first turn.
In order to win, Alok should remove O2 on his first turn.
Alok has no winning strategy.
Solution: Between special coins there are two gaps.
first of 2 coin
second of 95 coin
if anuj goes with 2 coin gap he will lose as it is even
if anuj goes with 95 coin gap he will win as it is odd & last turn will be his
Question17: Susan made a block with small cubes of 8 cubic cm volume to make a block 3 small cube long, 9 small cubes wide and 5 small cubes deep. She realizes that she has used more small cubes than she really needed. She realized that she could have glued a fewer number of cubes together to lock like a block with same dimensions, if it were made hollow. What is the minimum number of cubes that she needs to make the block?
a) 114 b) 135 c) 21 d) 71
Solution: The total volume (in terms of number of cubes) of the solid = 3*9*5 = 135
The total volume (in terms of number of cubes) of the hollow = (3-2)*(9-2)*(5-2)
= 21
so number of cubes required = 135-21 = 114
Question18: In the year 2002, Britain was reported to have had 4.3m closed – circuit television (CCTV) cameras – one for every 14 people in the country. This scrutiny is supposed to deter and detect crime. In one criminal case, the police interrogate two suspects. The ratio between the ages of the two suspects is 6:5 and the sum of their ages is 55 years. After how many years will the ratio be 8:7?
a) 11 b) 6 c) 10 d) 5
Question19: Given a collection of 36 points P in the plane and a point equidistant from all points in P, which of the following are necessarily true?
The points in P lie on a circle.
The distance between any pair of points in P is larger than the distance between X and a point in P
a) A and B b) neither A nor B c) B only d) A only
Solution: A only. B is not possible because line joining any two points in P becomes a chord which is always less than the radius (line joining X and any point in P) of circle
Question20: Spores of a fungus, called late blight, grow and spread infection rapidly. These pathogens were responsible for the Irish potato famine of the mid-19th century. These seem to have attacked the tomato crops in England this year. The tomato crops have reduced and the price of the crop has risen up.

How many gloves must she take out to make sure she has a pair of each color?
a)50 b) 8 c) 60 d) 42
Solution: in the first case the lady takes up 32 red color
then he takes up 24 y (cause he should take up pair)
then he takes up 1y+1blue
then 2blue(cause to make sure he has a pair of each color in hand)
32+24+2+2=60

b) There is more coffee in the first tumbler than water in the second tumbler
c) There is as much coffee in the first tumbler as there is water in the second tumbler
d) None of the statements holds true.
Question26: There are two water tanks A and B, A is much smaller than B. While water fills at the rate of one liter every hour in A, it gets filled up like 10, 20, 40, 80, 160... In tank B. (At the end of first hour, B has 10 liters’, second hour it has 20, and so on). If tank B is 1/32 filled after 21 hours, what is the total duration required to fill it completely?
a) 26 hrs b) 25 hrs c) 5 hrs d) 27 hrs
Question27: Middle – earth is a fictional land inhabited by Hobbits, Elves, dwarves and men. The Hobbits and the Elves are peaceful creatures who prefer slow, silent lives and appreciate nature and art. The dwarves and the men engage in physical games. The game is as follows. A tournol is one where out of the two teams that play a match, the one that loses get eliminated. The matches are played in different rounds where in every round, half of the teams get eliminated from the tournament. If there are 8 rounds played in a knock-out tournol how many matches were played?
a) 257 b) 256 c) 72 d) 255
Solution: let no. of teams be x
after first round there will be x/2 teams remaining
after second round there will be (x/2)1/2=x/4 teams remaining
similarly
after eight round there will be (x/2^8) teams will be remaining
but after eight round only the winner team is remaining
therefore x/256=1;
x=256;
next
in eighth round 2 teams will be competing
so there will be 1 match
in 7th round 4 teams =2 matches
similarly
in first round 256 teams=128 matches
what we require is
total no. of matches played=1+2+4+8+16+32+64=128=255
Question28: On planet korba, a solar blast has melted the ice caps on its equator. 9 years after the ice melts, tiny planetoids called echina start growing on the rocks. Echina grows in the form of circle, and the relationship between the diameter of this circle and the age of echina is given by the formula
d = 4*√ (t-9) for t ≥ 9
Where d represents the diameter in mm and t is number of years since the solar blast. Jagan recorded the radius of some echina at a particular spot as 7mm. How many years back did the solar blast occur?
a) 17 b) 21.25 c) 12.25 d) 12.06
Question29: Rearrange the following letters to make a word and choose the category in which it Ms RAPETEKA
a) Bird b) Vegetable c) City d) Fruit
Question30: Alok is attending a workshop “How to do more with less” and today's theme is Working with fewer digits. The speakers discuss how a lot of miraculous mathematics can be achieved if mankind (as well as womankind) had only worked with fewer digits. The problem posed at the end of the workshop is-
How many four digit numbers can be formed using the digits 1, 2, 3, 4 , 5 ( but with repetition) that are divisible by 4?
Can you help Alok find the answer?
a) 100 b) 125 c) 75 d) 85
Question31: A car manufacturer produces only red and blue models which come out of the final testing area completely at random. What are the odds that 5 consecutive cars of the same color will come through the test area at any one time?
a) 1 in 16 b) 1 in 125 c)1 in 32 d) 1 in 25
Solution: Prob of red = 1/2
Prob of blue = 1/2
Prob of 5consecutive colors is (1/2)^5
But there are two cases, cars are either all red or all blue so
Ans will be 2*(1/32)^5 ie 1 in 16
Question32: One day Alice meets pal and byte in fairyland. She knows that pal lies on Mondays, Tuesdays and Wednesdays and tells the truth on the other days of the week byte, on the other hand, lies on Thursdays, Fridays and Saturdays, but tells the truth on the other days of the week. Now they make the following statements to Alice – pal. Yesterday was one of those days when I lie byte. Yesterday was one of those days when I lie too. What day is it?
a) Thursday b) Tuesday c) Monday d) Sunday
Explanation:
On Thursday, Pal say truth i.e. yesterday (Wednesday) was one of those days when I lie. It’s true.
On the other hand, On Thursday, Byte lie i.e. yesterday (Wednesday) was one of those days when I lie too. It’s a lie. So both satisfied. Hence it’s Thursday.
Question33: Six friends decide to share a big cake. Since all of them like the cake, they begin quarreling who gets to first cut and have a piece of the cake. One friend suggests that they have a blindfold friend choose from well shuffled set of cards numbered one to six. You check and find that this method works as it should simulate a fair throw of a die. You check by performing multiple simultaneous trials of picking the cards blindfold and throwing a die. You note that the number shown by the method of picking up a card and throwing a real world die, sums to a number between 2 and 12. Which total would be likely to appear more often – 8, 9 or 10?
a) 8 b) All are equally likely c) 9 d) 10
Question34: A number when divided by D leaves a remainder of 8 and when divided by 3D leaves a remainder of 21. What is the remainder left, when twice the number is divided by 3D?
a) 13 b) cannot be determined c) 3 d) 42
Solution: suppose the no. is a
a = Dx +8 …….(1)
a = 3Dy + 21 …….(2)
So from 1 & 2 we get
D(x-3y) = 13
13 is prime so x-3y has to be 1
let x = 4 and y = 1
We get a = 60
2a = 120
So 120 when divided by 3D = 39
we get remainder as 3
So answer is 3
Question35: A toy train produces at least 10 different tunes when it moves around a circular toy track of radius 5 meters at 10 meters per minute. However, the toy train is defective and it now produces only two different tunes at random. What are the odds that the toy train produces 4 consecutive music tunes of the same type?
a)1 in 16 b) 1 in 4 c) 1 in 8
Solution: It can produce sound A , prob = 1/2 * 1/2 * 1/2 * 1/2 = 1/16
or sound B , prob = 1/16 (with the same logic)
So, probability of consecutive sound = 1/16 + 1/16 = 1/8
After the aptitude the results were announced at 8:00 pm in the night.I was very worried about my selection.I had done 30 questions but still I was worried about the cut off score.There is negative marking also.The cut off score is generally around 19,20.So if you do around 25 questions you are on the safer side.Just go through the previous papers.I was lucky to be the one among who were selected but then was the tension of next three rounds.
It was on the next day.So I would suggest for the technical interview read according to the branch in which you are as tcs people don’t ask you anything beyond it.And don’t try to fool them as they have google.com in front of them to verify us.So if you don’t know simply tell them.If you have some achievements in btech tell them about it.They are interested.My waiting time for interview started at 9 in morning.I was called at 9:30 at night.So after a long time duration I was not even a single bit tired due to my craze for TCS.There were 14 panels for the interview.I got panel 7 which constituted of the seniormost official of tcs and one another tcs person.They were famous for getting into the depth of technicality.That was the point when I was thinking that my bad luck wont leave me..But happened next was …I entered the room..
Me:May I come in Sir?
1st person:Yah sure please come in.
(I entered and wished them)
Me:Good evening Sir.
1st:Very good evening Harshita.So have a seat.
So how was the day Harshita?
Me:It was very nice sir.
1st :U had to wait for a long time.Wasn’t it tiring?
Me:Absolutely not sir.I enjoyed waiting.
1st:Ok harshita so tell me about urself..
Me:Told..about various presentations..prize at IIT,roorkee and proposal at IIT,Kharagpur..etc…
1st:Ok then tell me about the present research you are doing..
Me:Told about my research.
1st:If u are doing so much research so do you want to carry on it in future?
Me:Told
2nd :Tell me about high level and low level modulation?
Me:Told
1st:What is difference in diode and transistor?Give applications of both.
Me:Told.
2nd:What is the use of amplifiers?
Me:Told.
1st:Why tcs?
Me:I have got many reasons in pre placement talk so told..
1st:So y do u want to shift ur branch frm ece to it?
Me:Told.
(He was a bit impressed by my answers)
1st:Any questions for tcs?
Me:Asked about the passport seva.
1st:Told for about 10 minutes..
Me:Thank u sir.
1st:Now you can go harshita..
Me:Thank u sir..
(After one hour I was sent for the HR interview)

TCS LATEST PAPER 31
Hi,
This Durgesh Nandan Vishwakarma, from SLIET ,longowal Punjab.
TCS visited our college on 13th of sep;2011 (written) for recruitment .Its criteria was as usual 60 % through out, maximum two backlog and maximum of two year study gap. It’s written test is known as touch-stone. It is totally aptitude test containing mainly questions of probability, reasoning, ratio and proportion. They have provided us 500 sample question. All questions were from that sample question paper. Some of the question were repeated in my test like questions of probability and ratio and proportion was repeated 3 times in My test..
The test had 35 question to Be answered in 80 Minute. Some of the examples of my question were:-
1. The ages of two friends are in the ratio 6:5. The sum of their ages is 66.After how many years will the ages be in the ratio 8:7?
Answer: 12 years
2. (There was a long story, I'll cut short it). There are 5 materials to make a perfume: Lilac, Balsalmic, Lemon, Woody and Mimosaic. To make a perfume that is in demand the following conditions are to be followed: Lilac and Balsalmic go together. Woody and Mimosaic go together, Woody and Balsalmic never go together. Lemon can be added with any material. (Actually they had also mentioned how much amount of one can be added with how much quantity of the other; but that's not needed for the question.) All of the following combinations are possible to make a perfume EXCEPT:
Balsalmic and Lilac
Woody and Lemon
Mimosaic and Woody
Mimosaic and Lilac
Answer: Mimosaic and Lilac.
3. Anup and bhanu max and min game question.
4. X no of people write X no of lines of code in X minute then y no of line in Z minute can be written by ACB person? (Can not remember the data)
Most of the questions were last year repeat. Just go through those question From freshersworld.com. There are few sites like testfunda.com, m4math.com etc are very useful .
After my test in morning, the result of sort listed student was published in T & P department at evening . I think the cut-off should be around 23-25. I had attempted 31 question in which 1 or 2 were wrong. I was among selected students.
Next Day i.e. on 14th of Sep,2011 we went to SUS tangori, Mohali for Technical and HR interview.
My Technical Interview was as follow:-
Me: May I come In

This Durgesh Nandan Vishwakarma, from SLIET ,longowal Punjab.
TCS visited our college on 13th of sep;2011 (written) for recruitment .Its criteria was as usual 60 % through out, maximum two backlog and maximum of two year study gap. It’s written test is known as touch-stone. It is totally aptitude test containing mainly questions of probability, reasoning, ratio and proportion. They have provided us 500 sample question. All questions were from that sample question paper. Some of the question were repeated in my test like questions of probability and ratio and proportion was repeated 3 times in My test..
The test had 35 question to Be answered in 80 Minute. Some of the examples of my question were:-
1. The ages of two friends are in the ratio 6:5. The sum of their ages is 66.After how many years will the ages be in the ratio 8:7?
Answer: 12 years
2. (There was a long story, I'll cut short it). There are 5 materials to make a perfume: Lilac, Balsalmic, Lemon, Woody and Mimosaic. To make a perfume that is in demand the following conditions are to be followed: Lilac and Balsalmic go together. Woody and Mimosaic go together, Woody and Balsalmic never go together. Lemon can be added with any material. (Actually they had also mentioned how much amount of one can be added with how much quantity of the other; but that's not needed for the question.) All of the following combinations are possible to make a perfume EXCEPT:
Balsalmic and Lilac
Woody and Lemon
Mimosaic and Woody
Mimosaic and Lilac
Answer: Mimosaic and Lilac.
3. Anup and bhanu max and min game question.
4. X no of people write X no of lines of code in X minute then y no of line in Z minute can be written by ACB person? (Can not remember the data)
Most of the questions were last year repeat. Just go through those question From freshersworld.com. There are few sites like testfunda.com, m4math.com etc are very useful .
After my test in morning, the result of sort listed student was published in T & P department at evening . I think the cut-off should be around 23-25. I had attempted 31 question in which 1 or 2 were wrong. I was among selected students.
Next Day i.e. on 14th of Sep,2011 we went to SUS tangori, Mohali for Technical and HR interview.
My Technical Interview was as follow:-
Me: May I come In
TR: yes please
ME: Good Evening Sir
Tr:Evening , have a seat.
Me : Thanks.
Then he started reading my CV.
TR: Introduce yourself.
Me: told.
Tr.:My area of Interest?

A result of global warming is that the ice of some glaciers is melting. 16 years after the ice disappears, tiny plants, called lichens, start to grow on the rocks. ecach lichen grows approximately in the shape of a circle. The relationship between the diameter of this circle and the age of the lichen can be approximated with the formula: d=18*(t-16) for t > 16, where d represents the diameter of the lichen in millimeters, and t represents the muber of years after the ice has disappeared. Using the above formula, calculate the diameter of the lichen, 33 years after the ice has disappeared.

Alice and Bob play the follwoing coins oin a stack game. 100coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving up the topmost coin to another position in the stack. Alice starts and the players take turns. A turn consists of moving the coin on the top to a position I below the top coin (for some I between 0 and 100). We will call this an i-move )thus a 0-move impklies doing nothing). The proviso is that an i move canot be repeated. for example once a player makes 2-move, on subsequent turns neither player can make a 2-move. if the gold coin happens to be on top when it's a player turn then the player wins the game. Initially, the gold coin is the thiurd coin from the top.
In order to win, alice's first move should be a 0-move
in order to win, alice's first move can be a 0-move or a 1-move
in order to win, alice's first move should be a 1-move

NOTE:
1. TCS has a Dummy Questions. It means to any question if we solve the right answer the correct answer will not be in the options provided. So we shouldn’t attempt that question.
2. Although the TCS has the repeated questions in its aptitude test the formula to filter is the above mentioned methodology. What ever the questions we answered, unanswered, didn’t attempt appear as different colors so that they can easily identify since it is online test.
3. Depending On the College and no of students they are changing the written exam pattern. Not only have the 75 patterns, the questions come from Reasoning and CAT level,
4. Don’t mug up the answers they change the numerical so learn the procedure to solve the problems.
APPTITUDE TEST:
1. (1/2) of a number is 3 more than the (1/6) of the same number?
a) 6 b) 7 c) 8 d) 9
Sol:
Let the number be x,
((1/2)*x)=3+(1/6)*x,
Then solve x
2. There are two water tanks A and B, A is much smaller than B. While water fills at the rate of 1 liter every hour in A, it gets filled up like , 10, 20, 40, 80, 160 in tank B. (At the end of first hour, B has 10 liters, second hour it has 20 liters and so on). If tank B is 1/32 filled of the 21 hours, what is total duration of hours required to fill it completely?
a) 26 B) 25 c)5 d)27
Sol: for every hour water in tank in B is doubled,
Let the duration to fill the tank B is x hours.
x/32 part of water in tank of B is filled in 21 hours,

20. Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack.
Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coinis the third coin from the top. Then
a) In order to win, Alice's first move should be a 1-move.
b) In order to win, Alice's first move should be a 0-move.
c) In order to win, Alice's first move can be a 0-move or a 1-move.
d) Alice has no winning strategy.
Ans: a is the ans who ever wants to win there move should be 1-move….so many posted wrong ans..option a is right..

would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be
a) 0 b) 27 c) 18 d) 20
Sol : x+y-z = 11
x(y-z )= 18
x-y-z=2
just substitute those values and find the n value ie the answer..
if any logical explanation needed mail me.
20. Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack.
Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coinis the third coin from the top. Then
a) In order to win, Alice's first move should be a 1-move.
b) In order to win, Alice's first move should be a 0-move.
c) In order to win, Alice's first move can be a 0-move or a 1-move.
d) Alice has no winning strategy.
Ans: a is the ans who ever wants to win there move should be 1-move….so many posted wrong ans..option a is right..
21. For the FIFA world cup, Paul the octopus has been predicting the winner of each match with amazing success. It is rumored that in a match between 2 teams A and B, Paul picks A with the same probability as A's chances of winning. Let's assume such rumors to be true and that in a match between Ghana and Bolivia, Ghana the stronger team has a probability of 2/3 of winning the game. What is the probability that Paul will correctly pick the winner of the Ghana-Bolivia game?
a)1/9 b)4/9 c)5/9 d)2/3
Sol: (2/3)(2/3) + (1-(2/3))(1-(2/3))
22. 36 people {a1, a2, ..., a36} meet and shake hands in a circular fashion. In other words, there are totally 36 handshakes involving the pairs, {a1, a2}, {a2, a3}, ..., {a35, a36}, {a36, a1}. Then size of the smallest set of people such that the rest have shaken hands with at least one person in the set is
a)12 b)11 c)13 d)18
Ans: if we have choose 3 people that will be a set so that middle person can shake hands to two of them so it will be a small set.
Therefore 36/3 will be the ans= 12
23. After the typist writes 12 letters and addresses 12 envelopes, she inserts the letters randomly into the envelopes (1 letter per envelope). What is the probability that exactly 1 letter is inserted in an improper envelope?
a)1/12 b)0 c)12/212 d)11/12
Ans: b
24. There are two boxes, one containing 10 red balls and the other containing 10 green balls. You are allowed to move the balls between the boxes so that when you choose a box at random and a ball at random from the chosen box, the probability of getting a red ball is maximized. This maximum probability is
a)1/2 b)14/19 c)37/38 d)3/4
Ans: move 9 red balls to the box that contains green balls.
So now we have 1 box having 1 red and other box having 19 red and greenball.
Choose 9 red from 19 balls.
1 / 2 is the probability to choose the box.
(1/2) + {(1/2)*(9/19)}
14/19
25.A circular dartboard of radius 1 foot is at a distance of 20 feet from you. You throw a dart at it and it
hits the dartboard at some point Q in the circle. What is the probability that Q is closer to the center of the circle than the periphery?
a) 0.75 b) 1 c) 0.5 d) 0.25
Ans: d
26. By using 1, 2,3,4,5, how many 12 digit no. can be formed which is divisible by 4, repetition of no. is allowed?
Ans: (5) ^11
27. A hollow cube of size 5 cm is taken, with a thickness of 1 cm. It is made of smaller cubes of size 1 cm. If 4 faces of the outer surface of the cube are painted, totally how many faces of the smaller cubes remain unpainted?
900 488 500 800
28. Anoop managed to draw 7 circles of equal radii with their centres on the diagonal of a square such that the two extreme circlestouch two sides of the square and each middle circle touches two circles on either side. Find the ratio of the radius of the circles tothe side of the square.a)
a)1:(2+ 7√2) b)(2+ 7√2):1 c)1:(4+ 7√3) d)1:(2+ 6√2)
Sol:
The extreme circles will have radius perpendicular to sides..so the part of diagonal till the centre of cirlce will be sqrt(2)r[Make diagram and it will be clear]..now remaining portion is r , 5 more circles will contribute 10r and last circle will contributesqrt(2)r + r. total 12r + 2sqrt(2)r = sqrt(2) sideso ratio of r:s = 1/2+6sqrt(2

TCS LATEST PAPER 27
My experiences with the TCS hurdle!!
Hello friends, my name is Amit Sinha. I am a final year Electrical Engineering student of NSEC, Kolkata, under the Techno India Group. Recently Tata Consultancy Services had come to pay a visit to our college and the criterion were as follows:
1) Minimum 60% throughout
2) Maximum of 2 backlogs in the previous semester.
3) According to the WBUT curriculum, the percentage, corresponding to a given CGPA was to be calculate as (CGPA-0.75)*100..
Direct interview was arranged for those candidates who were having 75% or above throughout.. thus, 75% in classes 10th and 12th (which was to be calculated as total marks obtained in all the subjects divided by the total number of subjects) and a minimum CGPA of 8.25(equivalent to 75% subject to the rules) was the required criterion for the direct interview.
The rest of the lot had to appear for the online aptitude test, firstly and qualifying the same would make them eligible for the final interview round. So i was one of them who had to appear for the online aptitude test. The reporting time was 7.30 AM in the morning, at Techno India, Kolkata. We arrived right on time but we were made to wait for a long time. Eventually we were signalled to move to the room where the online test was scheduled to be held. The test was on the touchstone, which comprised of 35 questions and 80 minutes were allotted for the same. Rough sheets would be provided by the invigilators and additional would also be provided. The test paper would seem to be really easy if you are thorough with the questions given on www.freshersworld.com (the previous TCS papers), because all the questions were common. Once the test came to an end, we were told to wait in the seminar room. The results came within an hour. Almost all the students had cleared the aptitude round. The cut off was not known, though students who mentioned that they had attempted 22 questions out of a total of 35 had also made it through the aptitude round. Its better to score above 27 out of 35. I had attempted 29/35 questions. The various formalities which included document verifications and submission of the CV took place after the same results were declared.
The next hurdle was the final interview round. This was a deciding round and an elimination round as well. There were round 80 panels that had come for the interview process. We were instructed to move up to the respective class rooms from where we would be summoned for the interview rounds. My name was announced almost immediately and few other students, along with us were told to move up to a corridor. The classrooms in those corridors were filled with interviewers who were taking the interview of the students. You need to be ready with your documents, your CV and all necessary items. (though they had instructed that nothing but a pen would do it). My name was eventually called and i went up to the room. The interviewer who was supposed to interview me was leaving the room because of some reason and he walked up to me. I cordially wished him and he told me in an amiable manner, ”please don’t call me sir, call me Arvind”.. this was not so easy because in those strenuous and tense situations the same is not possible. The questions which he started with were:
1) introduce yourself
2) Being an electrical engineering student, why would you like to join TCS?( be ready with the ans if you happen to be of a stream other than CSE or IT)
3) What are the basic subjects you are having in your curriculum?
4) What is the difference between Computer Science and IT?
5) What type of Programming language is C?
6) You are having two companies A & B. What points will you look into before going for any one? (This was followed by a dangerous question)
7) You have 3 companies TCS, Wipro and IBM. Which one will you opt for?( friends, remember this is an eliminator question. Be ready with the answer with at least a reason or two in your support)
8) You have 10 members in your team, 4 are working and the rest are casual. What would be your idea?
9) You are busy, performing some important work and your colleague walks up to you and requests you to help him solve a problem, what would you do? Would you leave the current work and go to help him or would you simply balk?
10) How long will it take you to learn a programming language?(DONT!! Put any numerical figure as your answer.. you may end up screwing yourselves!!)
11) The nest 2-3 questions were from my projects and Tech Fests had participated in.
12) Do you have any preferred locations for posting?
13) Do you have any question for us?
The interview eventually came to an end when he told me that we would be informed regarding our results within a few days. Well my joy had no bounds when at 1.30 AM at night, we were looking at the list of the qualified students. I was one of them. 350+ students finally got selected. It was a matter of success for each and every successful student of our college.
You need to keep track of a few things before you go for the interview:
1) You need to be having adequate speaking skills. Its mandatory. If you have the slightest doubt that you may be weak at speaking and communicating in English, buck up and start reading English books, newspapers and all reading materials that comes your way. Talk to your friends in English. No need to feel shy because everyone has to start from a lower level.
2) Be strong with the computer subjects if you happen to be of the Computer Science stream. For other streams, C programming language is a must and be prepared with at least 2 departmental subjects.
3) Last but not the least, be confident and put your trust in the lord. YOU WOULD DEFINATELY SUCCEED!!!!!
ALL THE BEST TO ALL OF YOU.. GOD BLESS YOU!!
