67 is related to 74 following a certain logic. Following the same logic, 13 is related to 20.
To which of the following is 52 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

Given - 67 is related to 74 following a certain logic. Following the same logic, 13 is related to 20.
Logic = first number +7 = second number
67 → 74
67 + 7 = 74

and
13 → 20​
13 + 7 = 20

Now apply the same logic to 52:
52 + 7 = 59
Hence 59 is the answer.

Option C is correct.
