06. Ans: (a)
Solution:
Sum of the position of the first number and next two add upto 26
Q is 17, I is 9 and O is 15, K is 11
M is 13, M is 13 and K is 11, O is 15
Y is 25, A is 1 and W is 23, C is 3
So, term satisfying this relation is UESG.
Alternate Logic: The difference between first letters of the 2 given ratios is -4, +4, -4, +4.
Q (17) – M (13) = +4
I (9) – M (13) = -4
O (15) – K (11) = +4
K (11) – O (15) = -4
Following the same pattern, the correct answer is UESG.
07. Ans: (a)
Solution:
n na b is divisible by a b , when n is odd.
You can also follow a hit and trial method. Substitute n= 0, 1, 2, 3 and see if the value is
divisible by 11. You’ll find that the value is only divisible by 11 when n= 1 and 3, which gives
you (a) as the correct answer.

Solution
7 4 1 19! 2 3 5 7
co-prime numbers are called coprime if only positive integer that evenly divides both of
them is 1
So, Factors can be selected in 42 16 ways; hence, 8 pairs are possible.
Alternate Solution:
If p qN a b .........., where a, b, - - - - are prime numbers, then N can be written as a product
of two co primes in 2n-1 ways, where n is the number of prime factors to N. Here, n=4 (Since
the prime factors are 2, 3, 5, 7)
Hence the number of ways 9! Can be expressed as a product of two prime factors =24-1=8

Solution:
Let the three angles (in A.P) be x, x a, x 2a
Given that x 2a x a x , i.e. 2a a x a x
Hence the angles are in the form x, 2x, 3x. Let the 4th angle be P
Three cases exist when P is equal to one of x, 2x and 3x respectively.
Case1: P=x

Angles are 51.4,51.4; 51.4 2; 51.4 3
Since no angle is 90; we reject this possibility
Case 2: P=3x
