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 pattern followed here is as follows: (First number × 3) + 5 = Second number 14: 47 → (14 × 3) + 5 = 42 + 5 = 47 17: 56 → (17 × 3) + 5 = 51 + 5 = 56 12: 41 → (12 × 3) + 5 = 36 + 5 = 41 16: 52 → (16 × 3) + 5 = 48 + 5 = 53 (should be 53, not 52) So, 16: 52 is the odd number-pair.
