    Question

    Select the set in which the numbers are related in the same way as are the numbers of the following sets.
    (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 to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
    (16, 256, 16)
    (9, 81, 9)

    A.

    (4, 16, 6)

    B.

    (8, 64, 8)

    C.

    (12, 144, 10)

    D.

    (25, 625, 20)

    Correct option is B

    Information Given:
    (16, 256, 16)
    (9, 81, 9)

    Logic:
    Second number = (First number)² and Third number = √(Second number)

    Explanation:
    (16, 256, 16)
    16² = 256 ✔
    √256 = 16 ✔

    (9, 81, 9)
    9² = 81 ✔
    √81 = 9 ✔

    Check options:
    A: 4² = 16 ✔, √16 = 4 ≠ 6 ✘
    B: 8² = 64 ✔, √64 = 8 ✔
    C: 12² = 144 ✔, √144 = 12 ≠ 10 ✘
    D: 25² = 625 ✔, √625 = 25 ≠ 20 ✘

    Final Answer:
    (8, 64, 8)

    Final Correct Option:
    B
