Four number-pairs have been given, out of which three are alike in some manner and one is different. Select the one that is different.
Answer & explanation
Correct answer: option 4
The logic followed here is:
9 : 734 = 93 +5 = 734
7 : 348 = 73 +5 = 348
5 : 130 = 53 +5 = 130
8 : 516 = 83 + 5 = 517 ≠ 516
