89 is related to 78 following a certain logic. Following the same logic, 97 is related to 86. To which ofthe 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.)

Correct option is C

We are told that:
89 is related to 78
97 is related to 86
Step 1: Analyze the relationship between the pairs
89 → 78
89 – 11 = 78
97 → 86
97 – 11 = 86
Seems like the rule is: Subtract 11
Step 2: Apply same logic to 72
72 – 11 = 61
Final Answer: C. 61
