30 is related to 41 following certain logic. Following the same logic, 14 is related to 21. To which of the following numbers is 54 related, following the same logic?
(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /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.)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 69.
30 is related to 41 → 52 + 5 : 62 + 5
14 is related to 21 → 32 + 5 : 42 + 5
Similarly, 54 is related: → 72 + 5 : 82 + 5 = 69
