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.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 13: 506
The logic used here is:
(1st number)2 × 3 = 2nd number
Option 1: 12: 432
122 × 3 = 432
Option 2: 13: 506
132 × 3 = 507
This does not follow the logic.
Hence, Option 2 is the odd one out.
