Number analogy section deals with two types of questions:
I. Choosing a similarly related pair as the given number pair on the basis of the relation between the numbers in each pair.
II. Choosing a number similar to a group of numbers on the basis of certain common properties that they possess.

Given set : (63, 49, 35)

Option:
A. (72, 40,24)
B. (72, 48, 24)
C. (64, 40, 28)
D. (81, 63, 45)
Answer: D . (81, 63, 45)

Justification: Each set consists of numbers which are obtained by multiplying a certain number by 9, 7 and 5 respectively.
Thus, in the given set, 63 = 7 * 9, 49 = 7 * 7, 35 = 7 * 5.
Similarly, 81 = 9 * 9, 63 = 9 * 7, 45 = 9 * 5.
