Find the odd number pair: 2 : 8, 3 : 27, 4 : 32, 5 : 125.

A2 : 8

B3 : 27

C4 : 32 ✓ Correct

D5 : 125

Correct answer: (C) 4 : 32

Explanation

4 : 32 is the odd pair.

2 : 8, 3 : 27 and 5 : 125 follow n : n cubed (2^3 = 8, 3^3 = 27, 5^3 = 125).

In each the second number is the cube of the first.

4 cubed = 64, but the pair shows 32, not 64.

So the pair that is not n : n^3 stands apart.
