    Answer: (3) 36 years
    Explanation:-
    Let be the present age of A is 3X years   and age of B is X years.
    According to the question,
    (3X – 4)/(X – 4 ) = 4/1
    by cross multiplication,
    3X – 4 = 4X – 16
    X = 16 – 4
    X = 12
    Thus, the age of A is 3X = 3 x 12 = 36 years    and   the age of B is 12 years.
    Hence, the answer is (3) 36 years.
