Select the option in which the numbers are related in

Solution

The logic followed here is: The sum of the digits of the first number is multiplied by the sum of the digits of the third number to get the second number. For the set (13, 20, 14) → (1 + 3) × (1 + 4) = 4 × 5 = 20 Now checking the options: (a) (25, 60, 16) → (2 + 5) × (1 + 6) = 7 × 7 = 49 (b) (21, 42, 17) → (2 + 1) × (1 + 7) = 3 × 8 = 24 (c) (32, 40, 26) → (3 + 2) × (2 + 6) = 5 × 8 = 40 (d) (11, 28, 13) → (1 + 1) × (1 + 3) = 2 × 4 = 8
