    Question

    In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is
    same as that on the right side of ::?
    (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 — Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down
    13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

    X:112::15:Y

    A.

    X=l4,Y=l56

    B.

    X=12,Y=184

    C.

    X=10,Y=l48

    D.

    X=16,Y=192

    Correct option is B

    Given: 
    X:112::15:Y
    Logic: 1st × (1st letter - 3) + 4 = 2nd letter. 
    From the given options - 
    (b) X=12,Y=184
    12 × (12 - 3) + 12 × 9 + 4 = 108 + 4 = 112
    15 × (15 - 3) + 15 × 12 + 4 = 180 + 4 = 184
    Correct answer is (b).
