    Question

    If 5#3@3=12 and 7 # 2 @ 4 = 10, then what will be 2 # 9 @ 5?

    A.

    26

    B.

    32

    C.

    13

    D.

    29

    Correct option is C

    The pattern follows as

    5#3@3=12

    5×3 – 3 = 12

    15 – 3 = 12

    12 =12

    7 # 2 @ 4 = 10

    7 × 2 – 4 = 10

    14 – 4 = 10

    10 = 10

    Similarly,

    2 # 9 @ 5

    2 × 9 – 5

    = 18 – 5

    = 13
