    Question

    Which of the following letter-clusters will replace the question mark (?) in the given series to make it logically complete?

    MAN 7, PDQ 16, SGT 25, VJW 34, ?

    A.

    ULZ 40


    B.

    YMZ 43


    C.

    YNZ 43


    D.

    ZLU 36

    Correct option is B

    Given: MAN 7, PDQ 16, SGT 25, VJW 34,
    The numbers in the series are 7, 16, 25, 34, with a difference of +9 between consecutive terms:
    7+9=16
    16+9=25
    25+9=34
    34+9=43
    Thus, the next number is 43.
    Analyze the letters
    We observe each letter in the clusters MAN, PDQ, SGT, VJW:
    First letter progression (M, P, S, V):
    M → P → S → V, each moves forward by +3 in the alphabet.
    Next letter: V+3= Y.
    Second letter progression (A, D, G, J):
    A → D → G → J, each moves forward by +3 in the alphabet.
    Next letter: J+3=M.
    Third letter progression (N, Q, T, W):
    N → Q → T → W, each moves forward by +3 in the alphabet.
    Next letter: W+3=Z.
    Combine results
    The next letter-cluster is YMZ, and the corresponding number is 43.
    Final Answer: (B) YMZ 43
