3 is related to 8 following a certain logic. Following the same logic, 24 is related to 35. To which of the following is 99 related, following the same logic?
(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 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: D
Explanation
The correct answer is option 4 i.e. 120.
3 is related to 8 → 22 - 1 = 3; (2 + 2) × 2 = 8
24 is related to 35 → 52 - 1 = 24; (5 + 2) × 5 = 35
Similarly, 99 is related → 102 - 1 = 99; (10 + 2) × 10 = 120
