Select the set in which the numbers are related in the same way as the numbers of the following set.
(7, 9, 48)
(6, 8, 42)
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (11, 13, 72).
Logic: (Sum of first two digits) × 3
(7, 9, 48): (7 + 9) × 3 = 16 × 3 = 48
(6, 8, 42): (6 + 8) × 3 = 14 × 3 = 42
Similarly, (11, 13, 72): (11 + 13) × 3 = 24 × 3 = 72
