18 is related to 74 following a certain logic. Following the same logic, 22 is related to 90. To which of the following is 25 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: C
Explanation
The correct answer is option 3 i.e. 102.
18 is related to 74 → 18 × 4 + 2 = 74
22 is related to 90 → 22 × 4 + 2 = 90
Similarly, 25 is related → 18 × 4 + 2 = 102
