    Question

    Four letter-pairs have been given. out of which three are alike in some manner and one is different. Select the odd one.

    A.

    NY

    B.

    BL

    C.

    LW

    D.

    CN

    Correct option is B

    NY: N and Y have a difference of 11 positions in the alphabet (N=14, Y=25).
    BL: B and L have a difference of 10 positions (B=2, L=12).
    LW: L and W have a difference of 11 positions (L=12, W=23).
    CN: C and N have a difference of 11 positions (C=3, N=14).
    Upon observation, three of the pairs (NY, LW, CN) have a difference of 11 positions, while BL has a difference of 10.
    Thus, the odd one is (b) BL.
