TCS PAPER ON 11 MARCH AT LUCKNOW.
Hello friends .I m Ashok Maurya from INTEGRAL UNIVERSITY. my branch is
ECE.i appeared in the campus placements organized by TCS held at
Integral University on 11th & 12th march 08. There was no sectional cut
off, no upper cut off, but what i felt was that for critical reasoning u
must have to do at least one passage consisting of 4 questions correctly
.
WRITTEN TEST:
It was an online test which consisted of three sections: 1) Verbal. 2)
Quantitative Aptitude. 3) Critical Reasoning. VERBAL SECTION: It
consisted of 10 antonyms, 10 synonyms and two passage in which you have
to fill in the blanks with correct sentences. For antonyms do only the 5
model test papers & for synonyms prepare the exercises in the high freq.
word list. Though I got only 4 antonyms & 2 synonyms in the paper but it
is enough & rest of all I marked option c. For passage the time left was
very less. It’s a bit difficult but don’t worry, u can get through even
if u don know anything in verbal. Refer barrons 12th edition only.
QUANTITATIVE APTITUDE:
It consisted of 38 questions 40 mins. Very easy. All previous year
questions were repeated. Sometimes they don’t even change the data. I
will suggest that go through all d previous yrs papers.Some questions
which I remember are given below:
1. Exact power of 2?
Ans: 4096 , Hint: 2^10=1024,2^12=1024*4=4096.
2 Find the result of the following expression if, M denotes modulus
operation, R denotes round-off, T denotes truncation:
M(373,5)+R(3.4)+T(7.7)+R(5.8)
Ans: 19
3. What is the largest prime number that can be stored in a 9-bit
memory?
Ans: 509
4. Find the physical quantity in units from the equation:
(Force*Distance)/(Velocity*Velocity)
Ans: Ns2/m
5. Find the value of @@+25-++@16, where @ denotes "square" and + denotes
"square root".
Ans: 621
6. If G(0) = -1 G(1)= 1 and G(N)=G(N-1) - G(N-2) then what is the value
of G(6)?
Ans: -1 bcoz g(2)=g(1)-g(0)=1+1=2 g(3)=1 g(4)=-1 g(5)=-2 g(6)=-1
7. Convert the decimal number 310 to the base 6.
Ans: 1234
8. Find the missing number in the series: 2, 5, __ , 19 ,37, 75
Ans: 9
9. In a two-dimensional array, X(9,7), with each element occupying 8
bytes of memory, with the address of the first element X(1,1) is 3000,
find the address of X(8,5)?
10. What's the answer for that if A, B and C are 8 bit no's. They are as
follows: A -> 1 1 0 0 0 1 0 1 B -> 0 0 1 1 0 0 1 1 C -> 0 0 1 1 1 0 1 0
( - =minus, u=union) Find ((A - C) u B) =?
Ans: 187, Hint: To find A-C, We will find 2's compliment of C and them
add it with A, That will give us (A-C) 2's compliment of C=1's
compliment of C+1=11000101+1=11000110 A-C=11000101+11000110=10001001 Now
(A-C) U B is .OR. Logic operation on (A-C) & B 10001001 .OR . 00110011
The answer is = 10111011, Whose decimal equivalent is 187
11. Select the odd one out a. SMTP b.WAP c. SAP d. ARP
Ans: c
12. Select odd one- sql, db2, Sybase, http
Ans: http

d. -7i+j
Ans: a & c
14. Number of faces, vertices and edges of a solid planar cube. a.
12,8,6 b.4,6,8 c. 6,8,12 d. 6,12,8
Ans: c , Hint: faces=6, vertices=no. of points or corners where edges
meets=8, edges=12
15. A file is transferred from one location to another in 'buckets'. The
size of the bucket is 10 kilobytes. Each bucket gets filled at the rate
of 0.0001 kilobytes per millisecond. The transmission time from sender
to receiver is 10 milliseconds per bucket. After the receipt of the
bucket the receiver sends an acknowledgement that reaches sender in 100
milliseconds. Assuming no error during transmission, write a formula to
calculate the time taken in seconds to successfully complete the
transfer of a file of size N kilobytes.
Ans: (N/1000)*(N/10)*10+(N/100).........(not sure)
16. Which of the following is a singular matrix.

Ans: log 10x
20. In a city, temperature at noon varies according to -t^2/6 + 4t + 12,
where t is elapsed time. Find the percentage change in temperature from
3pm. to 6 pm
Ans: In equation first put t=3, we will get
25.5........................... (1) Now put t=6, we will get
42.............................. (2) So %change = ((42-25.5)/42)*100)
=39.3

Ans: for every one degree from east to west or west to east there is
time change by 4 minute.if we r going from east to west then subtract
the time otherwise add. here plane is going from 40 dgr east to 40 dgr
west.therefore there is total change of 80 dgr i.e by 80*4=320 minutes
or 5 hrs and 20 minutes.therefore time taken by plane is 2+8-5 hour 20
minutes i.e 6.40 pm.

There were 3 questions on vein diagram: some speak French, some speak
English…….& 3 questions on bar graph…..For these type of questions
r.s.agrawal is best.
CRITICAL REASONING:
This section consisted of 3 passages and 4 questions each(total 12
question). It was for 30 mins. All the questions were from 12 edition
Barron’s . They don even change the data and the order of questions.
They just cut copy paste from BARRONS 12 EDITION. Since it was online
test for us so everyone had different set of questions. For this section
I would suggest that do all the analytical passages, having 4 or more
questions, from the 5 model test papers of Barron’s 12th edition. if u r
not able to understand then just learn or mug up the answers. The
passages that I got were:
1. First question was red and brown marriage group……
2. Second was hotel Miramar.
3. Third was the Prahtu & Brahtu.
TECHNICAL AND HR INTERVIEW:
I had the technical & hr interview on the next day, in the afternoon
just after lunch. My first question was tell about ur self. I m from ECE
branch & since I haven’t mentioned any subject of interest so they
started asking the basics of electronics…….Like diode,rectifier(half
wave,full wave,center tapped,bridge rectifier etc….),characteristics of
diode,zener diode,avalanche breakdown, BJT, FET, uses of pnp transistor,
configurations(common base, CE, CC), gain factor ß etc……….. Then he
started asking from digital elex like multiplexer, demux, decoder, flip
flops(types, logic diagram, etc…..) , thyristors from power elex,some
quest were from communications…….. then he asked the basics of c++ &
asked me to write a program for finding largest of 3 nos. comparing a
no. not more than twice, in one line.
Hint: a>b?(a>c?a:c):(b>c?b:c)
Then they asked general questions like: Why tcs? u r from elex
background then why IT sector? etc……… Please remember whether u r a IT
or a non IT student they expect u to have some basic idea about c or
c++. He gave me some situations asked that what will u do in that
situation………..plz keep in mind that even if u don’t know the answer just
give a cute smile & be confident…….
I thought that my tech & hr were combined but after some time I got a
call for hr . there he asked the similar questions like tell abt ur
self, why tcs,etc……..then he asked about my father what he do & family
background……then he asked about the TATA crucible ( a quiz) that I
mentioned in my cv……asked my hobbies & asked that what I think on India
Vs Australia controversies……….DO prepare basic information about
tcs.(especially its vision mission n values……its CEO,chairman..company’s
status.recent news about comPANY….etc… & listen the pre placement talk
carefully). Finally they asked me do u want 2 ask anything?......so DO
prepare some qs 4 this……….What I asked was that :what I m lacking & what
u expect me to do to improve it , since I have still 1 yr to spend at
the college b4 joining, so it can benefit me as well as the company. He
smiled & answered.
My friends & my seniors helped me a lot…….i thanx to all of them…..the
main thing is that just be confident and have a smile on your face. That
is the secret to get through TCS. In the night the results were declared
& I was one among the students to be selected.
BEST OF LUCK!!!!!!!!!!! MEET YOU AT TCS.
