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:

12 : 156

18 : 342

17 : 307

14 : 210

Correct Answer:

17 : 307

The logic followed here is:

12 : 156 → 12² + 12 =156

18 : 342 → 18² + 12 = 342

17 : 307 → 17² + 17 = 306 ≠ 307(odd)

14 : 210 → 12² + 12 = 210
