CTS  aptitude questions


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 1-5 are based on the pattern with changed numbers 
as described above 

Questions 6-8 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


CTS numerical ability questions



1. Given the following functions
(1) f(n a b c ) = ac if n=1
(2) f(n a b c) = f( n-1 a c b) + f( 1 a b c) + f( n-1 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

CTS mathematical questions


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 2-5 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 - Pattern-matching type. 

Refer R.S Agarwal's book on Analytical Reasoning & TMHs 
Quantitative ability book by Edgar Thorpe.
