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.
Answer & explanation
Correct answer: option 4
The logic followed here is :
5 : 100
53 - 52 = 100
7 : 294
73 - 72 = 294
6 : 180
63 - 62 = 180
4 : 52
43 - 42 = 48 ≠ 52
