Question
Select the option in which the numbers are related in
the same way as the numbers in the following set: (13, 20, 14)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
