The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair.
Answer & explanation
Correct answer: option 1
The logic followed here Is:
(Ist number)2 - 2 × Ist number = second number
47 : 2116 = (47)2 - 2 × 47 = 2115 but 2116 is given which is odd
53 : 2703 = (53)2 - 2 × 53 = 2703
24 : 528 = (24)2 - 2 × 24 = 528
68 : 4488 = (68)2 - 2 × 68 = 4488
