    Question

    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.)

    A.

    70

    B.

    68

    C.

    72

    D.

    74

    Correct option is C

    Given:
    4 → 10, 34 → 40
    66 → ?
    Logic: Add 6 to the number.
    ​4 → 10
    4 + 6 = 10 
    ​34 → 40
    34 + 6 = 40 
    Similarly,
    ​66 → ?
    66 + 6 = 72 
    So, 66 → 72
    Thus, the correct option is: (c). 72
