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 from the rest.
Answer & explanation
Correct answer: option 1
The logic is
(Ist number)2 + 1 = second number
6 - 35 = (6)2 + 1 = 37 (odd) but 35 is given
4 - 17 = (4)2 + 1 = 17
5 - 26 = (5)2 + 1 = 26
7 - 50 = (7)2 + 1 = 50
