Question
The second number in the given number pairs is obtained
by performing certain mathematical operation(s) on the first number. The same operation(s) is/are followed in all the number-pairs except one. Find that odd number-pair.Solution
The logic followed here is: second number is the cube of the sum of the digits of the first number. In option 'A', first number = 236, second number = (2 + 3 + 6)³ = 1331 In option 'B', first number = 543, second number = (5 + 4 + 3)³ = 1728 In option 'C', first number = 622, second number = (6 + 2 + 2)³ = 1000 In option 'D', first number = 324, second number = (3 + 2 + 4)³ = 729 ≠ 625
