Select the option in which the numbers are related in the same way as are the numbers of the following set.
{9, 21, 16}
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. {36, 42, 64}.
The logic used here is:
{9, 21, 16}
√9 = 3
√16 = 4
(3 + 4) × 3 = 21
Option 1: {36, 42, 64}
√36 = 6
√64 = 8
(6 + 8) × 3 = 42
This follows the logic.
So, there is no need to check further options.
Hence, the correct answer is {36, 42, 64}.
