COGNIZANT Job Placement
Paper
This is
only a sample paper. We are not providing you with all the questions  just
some questions to give you a general idea of the test pattern.
SECTION I  8 questions based on series.
1. These questions involve interchange of letters in a word at particular
locations and also interchanging letters adjacent to those particular
locations.Certain other conditions may also be given
For eg.
Let the word be ABBAABA
If we apply 25 on this, it means we have to interchange the letters at
positions 2 and 5, also we have to change the letters adjacent to positions
2 and 5 i.e.from A to B and B to A.
A B B A A B after Step 1 i.e interchange of 2 and 5 becomes AABABB
Now change adjacent elements of 2 and 5...finally answer becomes
Ans: B A A B B A
Questions 15 are based on the pattern with changed numbers as described
above
Questions 68 are of the following type
To get AAABBD from BBBAAA what number should be applied:
a) 25
b) 34
c) 25 & 34
d) none
SECTION II
1. Given the following functions
(1) f(n a b c ) = ac if n=1
(2) f(n a b c) = f( n1 a c b) + f( 1 a b c) + f( n1 b a c ) if n > 1
Then what is the value f( 2 a b c ) = ?
Ans: f( 2 a c b ) = ab + ac + bc.
2. Similar question on functions.
3. [ Based on the function in the first question] For the function f( 4 a b
c ) the number of terms is...?
Hint f( 4 a b c ) = f( 3 a c b ) + f( 1 a b c ) + f( 3 b a c ) etc.
4. What is the value of the function f( 5 a b c ) = ?
SECTION III
Permutations and Combinations.
8 Questions.
1. r = number of flags;n = number of poles;
Any number of flags can be accommodated on any single pole.
1)r=5,n=5 The no. of ways the flags can be arranged ?
Questions 25 are based on the above pattern
6. r = 5 n = 3 . If first pole has 2 flags, third pole has 1 flag
How many ways can the remaining be arranged?
Questions 7.& 8. are similar to Question 6.
SECTION IV
Question consisting of figures  Patternmatching type.
Refer R.S Agarwal's book on Analytical Reasoning & TMHs Quantitative ability
book by Edgar Thorpe.
SECTION V
In this section first part of compound word is given. Select meaning of the
second part from the choice given:
1. Swan
2. Swans
3. Fool
4. Fools
5. Stare
6. Lady
For all above 4 choices are given.....
Eg. Swan > Swansong (compound word)
a) category b) music c) television d) none
Ans: Swansong is compound word. But song is not given as an option. so (b)
music is the answer.

viii)there were a couple of ( seven to be
precise)figures ( tetris type if u remember that game)
given in the main theme. The 10 questions that
followed showed patterns which were formed due to
combination of the 7basic figs. NOTE: the intersecting
part of the combined fig. always gets subtracted from
the total combination
Hello Shivesh
CTS paper was of diff pattern this time and there were
ateast 5 different sets of question papers given to
students. Of the type i recvd, as i told there wer
10x4 questions for 60 mins.
section:
4) last section( thats bcoz i remeber it well)
had meaningful words whose anagrams are nouns and
we hav to choose the best adjective from the list to
describe this noun:
ex: shore ( word given)
choices: a) roman b) spanish c) trojan d)....
ans: c) trojan
shore is anagram(jumbled form of) 'horse' and
trojanhorse is the best match
3) there were a couple of ( seven to be
precise)figures ( tetris type if u remember that game)
given in the main theme. The 10 questions that
followed showed patterns which were formed due to
combination of the 7basic figs. NOTE: the intersecting
part of the combined fig. always gets subtracted from
the total combination
2) This section had the funda of xOy where x and y
represented strings of Gs . The test was to find the
valid or invalid patterns with ref. to the rules
1) L=list of objects
ex:L={a,b,c,d} where a,b,c,d are objects
P(L) was a function( dont remembr xatly)
M(L) was another function defined etc
in the following questions P(x) etc were given to be
found out.
Note : this may take considerable amnt of time. so
take intelligent guesses
Section 1 : Functions.
Q: 1  8
Certain functions were given & based upon the
rules & the choices had to be made based on recursion.
This is time consuming, but u can do it.
Try to do it at the end. start from the last section.
L(x) is a function defined. functions can be defined as
L(x)=(a,b,ab) or (a,b,(a,b),(a,(b,b)),a,(b,b))....
two functions were given A(x) & B(x) like
if l(x)=(a,b,c) then A(x)=(a) & B(x)=(b,c)
i.e., A(x) contains the first element of the function only.
& B(x) contains the remaining, except the first element.
then the other two functions were defined as
C(x) = * if L(x) = ()
A(x) if L(x) = () & B(x) != ()
C(B(x)) otherwise
D(x) = * if L(x) = ()
** if B(x) = ()
A(x) if L(x) != () & B(x) != ()
D(D(x)) otherwise
now the Questions are,
1 : if L(x) = (a,b,(a,b)) then C(x) is ?
(a): a (b): b (c): c (d): none
2 : if L(x) = (a,b,(a,b)) then find D(x)
same options as above
3 : if L(x) = (a,b,(a,b),(b,(b))) find C(x)
4 : ~~~~~~~~ find D(x)
5 : if L(x) = (a,(a,b),(a,b,(a,(b))),b) then find c(x)
6 : ~~~~~~~~ find D(x)
7 : if L(x) = (a,b,(a,b)) then find C(D(x))
8 : ~~~~~~~~ find D(C(x))
Section 2 : Word series
Q's : 9  16
This is one of the easiest section. Try to do it at first.
if S is a string then p,q,r form the substrings of S.
for eg, if S=aaababc & p=aa q=ab r=bc
then on applying p>q on S is that ababaabc
only the first occurance of S has to be substituted.
if there is no substring of p,q,r on s then it should not be
substituted.
If S=aabbcc, R=ab, Q=bc. Now we define an operator R Q when
operated on S, R is replaced by Q, provided Q is a subset of S,
otherwise R will be unchanged. Given a set S= ………., when R Q,
P==
672; R, Q
 P operated successively on S, what will be new S? There will be 4
=
: if s=aaababc & p= aa q=ab r=bc then applying p>q, q>r & r>p will
give,
(a): aaababc (b): abaabbc (c): abcbaac (d): none of the
a,b,c
10: if s=aaababc & p= aa q=ab r=bc then applying q>r & r>p will
give,
11: if s=abababc & p= aa q=ab r=bc then applying p>q, q>r & r>p will
give,
12: if s=abababc & p= aa q=ab r=bc then applying q>r & r>p will
give,
13: if s=aabc & p=aa q=ab r=ac then applying p>q(2) q>r(2) r>p
will
give,
(2) means applying the same thing twice.
14: similiar type of prob.
15: if s=abbabc p=ab q=bb r=bc then to get s=abbabc which one should be
applied.
(a): p>q,q>r,r>p
16: if s=abbabc p=ab q=bb r=bc then to get s=bbbcbabc which one should
be
applied.
Let us consider a set of strings such as S=aabcab. We
now consider two
more sets P and Q which also contain strings. An operation
P>Q is defined in
such a manner that if P is a subset of S, then P is to be
replaced by Q. In
the following questions, you are given various sets of
strings on which you
have to perform certain operations as defined above. Choose
the correct
alternative as your answer.
(the below are some ques from old ques papers)
21. Let S=abcabc, P=bc, Q=bb and R=ba. Then P>Q, Q>R, R
>P changes S to
(A) ............ (B) abcabc (C) ............
(D) none of A,B,C
22. Let S=aabbcc, P=ab, Q=bc and R=cc. Then P>Q, Q>R, R
>P changes S to
(A) ababab (B) ............ (C) ............
(D) none of A,B,C
23. Let S=bcacbc, P=ac, Q=ca and R=ba. Then P>Q, Q>R, P
>R changes S to
(A) ............ (B) ............ (C) bcbabc
(D) none of A,B,C
24. Let S=caabcb, P=aa, Q=ca and R=bcb. Then P>Q, P>R, R
>Q changes S to
(A) ............ (B) ............ (C) ............
(D) none of A,B,C
Section 3 : numerical series

Section 5 : Verbal
if u have a very good vocab. then this section is managable.
two words together forming a compound words were given.
the q's contained the second part of the compound word.
the first word of the compuond word had to be guessed.
then its meaning had to be matched with the choices.
if the word is "body"
then its meaning of its first part is..
its really tough to guess..
