    Question

    Which of the following letter-number clusters will replace the question mark (?) in the given series to make it logically complete?
    NQ27, MP38, LO49, KN60,  ?

    A.

    B.

    JN72

    C.

    D.

    JN71

    Correct option is A

    Given series:
    NQ27 → MP38 → LO49 → KN60 → ?
    Logic: letter -1 and number +11
    First letter pattern
    N → M → L → K → ?
    N (14) - 1 = M (13)
    M (13) - 1 = L (12)
    L (12) - 1 = K (11)
    K (11) - 1 = J (10)
    Second letter pattern
    Q → P → O → N → ?
    Q (17) - 1 = P (16)
    P (16) - 1 = O (15)
    O (15) - 1 = N (14)
    N (14) - 1 = M (13)
    Number pattern
    27 → 38 → 49 → 60 → ?
    38 - 27 = 11
    49 - 38 = 11
    60 - 49 = 11
    Next number: 60 + 11 = 71
    Correct answer is (a) JM71.
