    Question

    21 is related to 220 by certain logic. Following the same logic, 72 is related to 781. To which of the following is 27 related,following the same logic? (NOTE : Operations should be performed on the whole numbers, without breaking down thenumbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc., to 13 can beperformed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

    A.

    290

    B.

    286

    C.

    340

    D.

    316

    Correct option is B

    Given: 21 → 220, 72 → 781, 27 → ?
    Logic: Multiply the first number by 10, then add the difference between the first number and 11.
    For 21: (21 × 10) + (21 - 11) = 210 + 10 = 220
    For 72: (72×10) + (72 - 11) = 720 + 61 = 781
    Now apply the same logic to 27:
    For 27: (27 × 10) + (27 - 11) = 270 + 16 = 286
    So, 27 relates to 286.
    Thus, the correct option  is (B).
