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 : 4718, 5617, 6312, 8314
In all numbers, the product of first and last digits is a multiple of the sum of middle two digits.
Thus, 4 * 8 = 32 is multiple of (7 + 1) i.e. 8,
5 * 7 = 35 is a multiple of (6 + 1) i.e. 7 and so on.
