89 is related to 78 following a certain logic. Following the same logic, 97 is related to 86. To which of the following is 72 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. 61.
The logic followed is:
89 is related to 78 → 89 - 11 = 78
97 is related to 86 → 97 - 11 = 86
Similarly, 72is related to ? → 72 - 11 = 61
Thus, 72 is related to 61.
