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 2
The logic is :
(Ist number ÷ 2)2 = second number
30 : 225 = (30 ÷ 2)2 = 225
24 : 130 = (24 ÷ 2)2 = 144 but 130 is given (odd)
20 : 100 = (20 ÷ 2)2 = 100
14 : 49 = (14 ÷ 2)2 = 49
