from the rest by a line, .i.e the point lies on one side of the line while the others lie on the
other side.
The number of 1-sets of P is denoted by n1(P). The minimum value of n1(P) over all
configurations P of 5 points in the plane in general position(i.e no three points in P lie on a
line) is
a)3 b)5
Ans: 5
c) 2
d)1
Q2. The citizens of planet nigiet are 8 fingered and have thus developed their decimal
system in base 8.
A certain street in nigiet contains 1000 (in base 8) buildings numbered 1 to 1000.
How many 3s are used in numbering these buildings?
a) 54 b) 64 c) 265 d) 192
Ans: 192
1’s place – 8*8-64
10’s place- 8*8-64
100’s place- 64 --total 192
Sometimes base value is chang like: 9finger, 1 to 100(base 9)
Q3. Given 3 lines in the plane such that the points of intersection form a triangle with sides
of length 20, 20 and 30, the number of points equidistant from all the 3 lines is

Q4. Hare in the other. The hare starts after the tortoise has covered 1/5 of its distance and
that too leisurely3. A hare and a tortoise have a race along a circle of 100 yards diameter.
The tortoise goes in one direction and the. The hare and tortoise meet when the hare has
covered only 1/8 of the distance. By what factor should the hare increase its speed so as to
tie the race?
a) 37.80 b)8 c) 40 d) 5
Ans: 37.80
We preceed as follows:
After tortoise covers 1/5th distance hare starts the race
When hare covers 1/8th of distance tortoise meets hare
So distance covered by tortoise = 1-(1/5 + 1/8)
= 27/40
Time taken by both is same
time = dist/speed
So (dist/ speed) of tortoise = (dist / speed) of hare
let speed of tortoise be t and of hare be h
27/40t = 1/8h
h = (40/(8*27) )* t = 5/27 * t
Now for the next part hare has to cover 7/8 th distance when tortoise covers 1/8 th distance
so we get
1/8t = 7/8h
h = 7t
so the factor by which h's speed increases = 7t/ (5/27 * t)
which is 37.8
So answer is 37.8
Q5. Here 10 programers, type 10 lines with in 10 minutes then 60lines can type within 60
minutes. How many programmers are needed?
a) 16 b) 6 c) 10 d) 60
Ans: 10
10*10 / 10 = 70*x / 70 --10

Q6. Alok and Bhanu play the following min-max game. Given the expression
N=9+X+Y-Z
Where X, Y and Z are variables representing single digits (0 to 9), Alok would like to
maximize N while Bhanu
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
The Q's concept is same but the equation of N's is changing.
Q7. 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: d
Q8. 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
Ans: 5/9
c)5/9
d)2/3
ghana wining and paul pickin ghana prob = 2/3
similarly for bolivia = 1/3
So answer = 2/3 * 2/3 + 1/3 * 1/3 = 5/9
Q9. 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
Let the 1st person be in the set...now he shakes hands with 36th and 2nd..so we choose the 4th person
to be in the set as he shakes with 3rd and 5th..so basically we choose every 3rd member of the
circle..so minimum no. of people reqd in the set are 12

2) Paul the octopus who has been forecasting the outcome of FIFA world cup matches with
tremendous accuracy has now been invited to predict ICC world cup matches in 2011. We
will assume that the world cup contenders have been divided into 2 groups of 9 teams each.
Each team in a group plays the other teams in the group. The top two teams from each
group enter the semi finals (after which the winner is decided by knockout).

Technical Round(TR): 28th Sept
My friends faced simple C programs and briefly about project. Now It's my turn, he asked
me about my self and about my main project nearly 35 minutes and 2 simple
Technical questions.
You should prepare C programs like reverse of a number, palindrome, fibonacci, even
number series, odd number series etc. and also data structure concepts.
MR round: Next day
This round is horrible for me, I faced some Technical questions here also.
He asked some basic concepts, i answered those questions correctly and confidently but he
argued with me that your answers are wrong then i told my answers are correct sir, then he
gave a horrible statement i.e "You think that I am not able to write even a simple C
program also" it was strange to me but i managed the situation. After some time he said
that
"Ok Mr. Gautam even you are not pefect in basic cinsepts how can i select you? So you can
go now try again after 6 months". He repeated this for 4 times, each time i smiled and
justifying my answer, he again repeated the same for 5th time too strange for me, at that
time i get up from the chair and again with a smile i asked that "Shell I wait at out side sir?"
then with a smile he said that "Ok Gautam you are promoted to H.R round".
I was very happy after clearing the M.R round. I proceeded to H.R round with a lot of
confidence.
H.R Round:
Here also i faced some Technical questions and H.R asked me that,
1) Tell me about your self?
2) Tell me any 2 incidents you want to share with me?
3) Why your % decreased in B.Tech? (As i had 77% in diploma, 73% in X , 68 in my
B.Tech)
4) Your strengths? (very frequnet qiestion but be prepared)
5) Your family?
6) How you ranked your self compared with your friends?
Rule 1: Prepare yourself on the following topics; Just brush up your basics: ages,
percentages, ratio and proportion, numbers, time and distance, sequence, time and work,
probability, permutation and combination & blood relation. {Here probability and per/com
is optional because it carries only 3-4 questions on it.}
Rule 2: Go through the previous papers in fresherworld of this test. I have also giving you
some relevant questions which appeared in our test.
Rule 3: Try to solve the questions by yourself; don't memorize them because data will be
changed.
Rule 4: Try to just interchange the data of the questions and solve them faster and faster.
The Time Management is a important skill often tested in aptitude test. So by practicing the
questions given below try to develop speed and accuracy.
Rule 5: Speed reading is a important part of this test as all the questions do have some
irrelevant data. So in these 3 days of preparation, try to find the relevant data from the
question and read very fast.
Tricks for aptitude test:
1) You will be asked to answer 35 questions in 60 minutes. At the beginning, don’t even
think to answer all questions.
2) Just go through all the 35 questions and solve the easy ones. Every paper consists of
minimum 15-17 easy questions and rest of them moderately difficult.
3) Try to answer the easy ones 15-16 questions out of 35 within 45 mins and also write the
individual number of moderately easy ones or mark them [that u think can do within 3-4
mins ] in the scratch paper.
4) Last 12-15 mins of the exam, try to solve the marked ones, atleast of 5 them.
5) The difference between you and others will lay answering marked ones, so try to solve
the easy 15-16 as fast as you can. [Caution: you try to believe that u can acquire 100%
accuracy in easy questions; so complete the easy questions of entire range question
number 1 to 35 within 40-45 mins.]
5) So after the time is completed, you will find urself answering 22-24 questions without
any rigorous preparation. Those who r a bit slower in calculations can also clear this test by
my plan. And cut off, as I already mentioned, lies below 20 around 18-19.
6) Last but not the least, don't try to mark the questions you are not absolutely sure; as the
paper consists of negative marking, you will not be able to meet the cutoff.

Ans is : a-b here 785-235= 550 thats it.
6. In school there are some bicycles and 4 wheeler wagons. One Tuesday there are 190
wheels in the campus. How many bicycles are there?
Ans: 15
Thought process : b*2+w*4=190 i.e. , b+2w=95 now see u ca not solve 2 unknowns fron
1 eqation, so just plot options here to get the right answer and verify if you are getting
integers as vales of B and W.
7. There are two persons paul and Jay .Paul lies on Monday,Tuesday,Wednesday and the
remaining days he speaks truth.Jay lies on Thursday,Friday,Saturday and the remaining

that yesterday is the day one among those I lie. Jay also says that yesterday I also lie.
what is that day?
a) Sunday. b) Tuesday. c) Thursday. d) Wednesday
[Thought process: Now this day cannot be Sunday because in Monday paul speaks truth and
Sunday everyone tells truth. So it must be weekdays. Again, Tuesday can not possible
because Monday and Tuesday paul speaks truth. In case of thrus day, paul speaks lie and
Wednesday he speaks true. And joy speaks truth in thrusday and he speak lies in
Wednesday. So, thrusday is the answer.
8. A father has 7 penny’s with him and 1 water melon is for 1p, 2chickoos for 1p, 3 grapes

1. Never Guess an answer . Attend only the questions you are reasonably certain of
answering correctly . (I attended exactly 30 questions , Never guessed any question
randomly.
2. If you dont get the answer in the first try or you get stuck up quickly skip the question .
Come back to it later if you have time. ( I attended the first question skipped 8 questions
before answering the next question).
3. Read the question fully once and find out what they are asking . Most of the time they
give a lot of irrelevant data to confuse you. For example they may ask a problem on ages
but may also give you data on blood relations (i have 2 brother and 2 sisters. You have to
correctly deduce the fact that you only need information related to Age and the rest is
irrelevant data .
4. Try not to panic at the sight of those long questions. Most problems are very simple
which require you to do some logical thinking with a clear mind.
5. There will be certain questions which will be very simple but will have small twists .
6. Most questions asked have a fixed pattern. A friend of mine attended the interview on
21st (she too got selected). Most of the questions i got were similar to the ones she got with
slight changes introduced (learn the logic dont mug up the answer) .
Some of the questions which I remembered are as given below.

added so he gets the ratio of 6:7.(Not exact question but something like that)
11) A tank fills in the squence of 10, 20 ,40,80.... (means 10 litre in 1 hr, 20 litr i 2nd nd
so). If at the 4th hour the tank is 1/4 full when will it be full?
Ans: x/4=80
That means capacity of tank is 320 litres. From the series we can see that in 5th hr it's 160
nd then in 6th hr it's 320 so answer is 6
12) 2 very simple questions on ages like if 3 years back i was 2 times of my friends age and
so and so. If you know the basic concept you will be able to solve that.
13) There are only bicycles and 4-wheelers in the parking. If the total number of wheels are
240.

4) 6 persons standing in queue with different age group, after two years their average age
will be 43 and seventh person joined with them. hence the current average age has become
45. find the age of seventh person?
Solution: Here the question appear as an easy one, but carried a lot of unwanted sentences
and unwanted datas (i dint mention above) in exam which may confuse you on solving
technique.
5) Let x be current average age of first 6 persons in queue and current age of seventh
person be y. Then 6x will become the sum of those 6 persons age. Now, let compute the
sum of those 6 persons after two years, 6x+12 (as each and individual increase their age by
2). hence its average become (6x+12)/6 = 43 (give in question itself). So now we can
compute x from above equation. (x = 41, 6x = 246).
Let now we compute y, ((6x+y)/7) = 45, as we have value of x, compute y.
Ans: 69
6) Horse started to chase dog as it relieved stable two hrs ago. And horse started to ran
with average speed 22km/hr, horse crossed 10 mts road and two small pounds with depth
3m, and it crossed two small street with 200 mts length. After traveling 6 hrs, 2hrs after
sunset it got dog. compute the speed of dog?
Ans: As we have speed and travel time of horse, we can get distance travelled by it.
Hence d = 22*6 = 132km,
Exactly this 132km was travelled by dog in 8 hours (as it started two hours earlier).
Hence speed of dog = 132/8 = 16.5km/hr
Ans: 16.5km/hr.

Technical Interview:
I got my interview schedule after four days in TCS Office Noida but lots of frends got dere
schedule on the day of paper. So be prepared mentally for interview n yeah be well dressed
it makes really a positive impact.
The interviewer was a beautiful lady the near about 28 years old.She welcomed me when
i entered in the room.My interview continued till 20mins.Imp Instruction if u r from Non cs
background den u can say u don't have much idea about s/w field then they asked u about
ur subjects but u have to impress him by knowledge of ur field n give them assurance that
u will do really good at a time of ur training.
* Tell me about ur self?(u have to tell about u n ur family background)
* My strength n weakness.(Be prepared for this question).
* About My final year project. (You have to tell whatever you done, its depend on. So
whatever you speak be confident)
* About summer training.(U have to specify about whatever u learn there they can ask u
simple ques regarding training)
* MY favourite subjects(I told DBMS, so she asked me about languages used in DBMS, Sql
queries, and about normalization etc.) ( It's really simple beccause this is in your hand to
tell a specific subject and they will ask you simple questions regarding your subject. It's not
necessary to give answer of all questions if you don't know say confidently i don't know.)
* She asked me About computer languages i said, i am comfortable in C and C++. So she
asked me what is a different between C and C++, Oops concepts, Different between Static
and final, write a program for palindrome. (Prepared for Some program Like (palindrome,
Fibonacci, Recursion, Strings, Factorial etc.)
* Generally they asked about your CV stuffs so make your CV according to your comfort
zone. May be they can ask something different from your CV but in that case you can easily
say i have no idea. In my case they asked about Unix commands.
Frankly speaking interview was so good because you have need to show that you
technically sounds better. So be prepared for the interview.
After technical we called for MR(Managerial round)
It was just a 7-8 min round.
They can ask you technical or puzzles or about your hobbies anything. So don't worry for
this round.
* The interviewer asked me about my hobbies, my family background.
* He gave me a puzzle like (a candle burns in 60min. Then how can two candles can burn
in 90min. Ans we can burn a candle first n in 60 min this will burn completely den we will
burn second one from both of end so it would take 90 min to burn both of candles.)
* Then he suddenly changed the question and said now you have 45 min to burn both of
candles and i couldn't do but he gave me 4 min to solve and insisted me luckily i got the
right answer and i replied. we would burn first candle from both of end and at same time we
would burn second candle from starting point so in 30 min the first one will burn completely
and second will burn half then we will burn second burning candle from another point also,
So in this way both of candles will burn in 45min.
* He asked me to write a simple C program to add two numbers and picked a questons like
roll of void main(), getch(), and about some header files.
Guys if you are worry about puzzles then frankly speaking look for some basic puzzles of
Shakuntla Devi. My be they can ask you puzzle.
HR Round:
This round was just of 2-3 minutes.
* They asked me how was my Technical round.
* Have i been placed in anywhere else(I replied yeah in infosys also, i don't know what
impact of this would be on her)
* Then she asked if i would been placed in infosys then why would i join TCS(i replied
because of work culture and ethics in TCS)
* At last she said me "Ok rahul we have done, you can go now".

I have done only 19 problems out of 35, but i am very much sure that all i made were 100% right. In
last 5 min i did not solve any problem but still i holded my nerve and didnot make any guess, all my
friends made 23-24 questions even one of my friend did 28 questions, at that time i was very much
depressed, i thought i need to solve one more problem. But when the result was announced i have
cleared the aptitude and some of my friends who solved more question than me unfortunately not
cleared the aptitude just because of they made some guesses so my suggestion is that please don't
make any guess.
After that there is a form fill-up part, and next the my interview was held, truely speakng friends i
could not sleep at that night and going to the interview hahahha. Sometimes i felt i was sleeping just

Ohh God it's took too much time almost 1 hour.
1. In lengthy questions first 1 to 3 lines used to be unnecessary time waste information, and the
problem correctly starts from 3 or 4 th line.So, read the question fastly with in few seconds & try to
know from where the question starts.
2. Among 35 some questions between 8 to 10 are given direct question without unnecessary
matter.So, friends when u feel a question is lengthy or u can't solve it just leave it go to others
(maybe be other questions r direct).
3. I think it will be better to have a view of all bits by half an hour doing all known or easy bits
because we can't say where easiest bit will be because I saw 1 easy bit in last 20 sec and I was
unable to attempt it.
4. Take calculator with you to written exam ,they will allow it.It makes ur work easier.
Coming to preparation for written test it is enough if go through examples and 1st exercises in R.S
Aggarwal
topics include ratio, average, age problems etc.
Never try to guess and answer. I have attempted 21 out of 35 no guess work .
I got a mail that i cleared written exam.

Some other questions:
1.6 persons standing in queue with different age group, after two years their
average age will be 43 and seventh person joined with them. hence the
current average age has become 45. find the age of seventh person?
Ans: Let x be current average age of first 6 persons in queue and current
age of seventh person be y. Then 6x will become the sum of those 6
persons age.
Now, let compute the sum of those 6 persons after two years,
6x+12 (as each and individual increase their age by 2). hence its average
become
(6x+12)/6 = 43
=>x+2=43
=>x=41
Let now we compute y, ((6*41+y)/7) = 45,
y= 69

Given that B fills up at the rate 10,20,40 etc...
This is a geometric progression where a = 10 r = 2
so after 21 hrs lts in B = a*r21
= 10 * 221
This is equal to 1/32 volume of B
SO TOTAL VOLUME OF B = 32 * 10 * 2^21
which is =10 * 2^26
So hrs required to fill up B is 26
