Select the set in which the numbers are related in the same way as the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/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)
(12, 42, 7) (13, 52, 8).
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. (9, 18, 4)
The logic used here is:
(12, 42, 7) = 12 × 7 = 84, 42 × 2 = 84
(13, 52, 8) = 13 × 8 = 104, 52 × 2 = 104
Similarly,
(9, 18, 4) = 9 × 4 = 36, 18 × 2 = 36
