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 4
The logic is:
(Ist number)2 + Ist number
22 : 506 = 222 + 22 = 506
14 : 210 = 142 + 14 = 210
17 : 306 = 172 + 17 = 306
11 : 142 = 112 + 11 = 132 but 142 is given (Odd)
