Question:

Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the number-pair that is different.

Options:

30 : 225

24 : 130

20 : 100

14 : 49

Correct Answer:

24 : 130

Explanation:

The logic is :

(Ist number ÷ 2)² = second number

30 : 225 = (30 ÷ 2)² = 225

24 : 130 = (24 ÷ 2)² = 144 but 130 is given (odd)

20 : 100 = (20 ÷ 2)² = 100

14 : 49 = (14 ÷ 2)² = 49
