Find the odd number pair: 14 : 56, 12 : 36, 23 : 92, 15 : 35.

A14 : 56

B12 : 36

C23 : 92

D15 : 35 ✓ Correct

Correct answer: (D) 15 : 35

Explanation

15 : 35 is the odd pair.

14 : 56, 12 : 36 and 23 : 92 give a whole-number multiple (56/14 = 4, 36/12 = 3, 92/23 = 4).

In each the second number is a whole multiple of the first.

35 / 15 = 7/3, not a whole number.

So the pair without a whole multiple stands apart.
