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) are followed in all the number pairs, EXCEPT one. Find that odd number pair.Solution
The logic followed here is as follows: Second number = (First number - 5) X 2 1) 32: 54 → (32 - 5) X 2 = 54 2) 28: 46 → (28 - 5) X 2 = 46 3) 11: 12 → (11 - 5) X 2 = 12 4) 17: 28 → (17 - 5) X 2 = 24 ≠28Â
