Select the set in which the numbers are related in the same way as are 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.)
(4, 16, 32)
(6, 36, 72)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (9, 81, 162).
(4, 16, 32) → 42 = 16; 16 × 2 = 32
(6, 36, 72) → 62 = 36; 36 × 2 = 72
Similarly, (9, 81, 162) → 92 = 81; 81 × 2 = 162
