4 is related to 10 following a certain logic. Following the same logic, 34 is related to 40. To which of the following is 66 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.)

Answer 1

The logic followed here is:

4 is related to 10 → 4 + 6 = 10

And,

34 is related to 40 → 34 + 6 = 40

Similarly,

66 is related to → 66 + 6 = 72

Hence, "Option 1" is the correct answer.
