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.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 9:64.
The logic used here is: (1st number) + 1 = a, a2 = 2nd number
Option 1: 3: 16 → 3 + 1 = 4, 42 = 16 This follows the logic.
Option 4: 9:64 → 9 + 1 = 10, 102 = 100 This does not follow the logic.
