    Question



    Three years before, the average age of A, B and C is 36 years and the sum of ages of A and B after 2 years is 76 years. If C is 6 years younger than A, find the age of B.

    A.

    12 years

    B.

    15 years

    C.

    13 years

    D.

    21 years

    E.

    19 years

    Correct option is D


    Sum of the present ages of A, B and C =36×3+9=117 years …..(I)
    Sum of the present ages of A and B = 76-4=72 years ……. (II)
    From (I) & (II)
    Present age of C = 117-72 = 45 years
    Present age of A = 45+6=51 years
    So, present age of B = 72-51=21 years
