    Answer: (4) 60 years
    Explanation:-
    Let be the age of daughter is X years.
    Then, age of father = 3 X
    The age of mother = 3 X – 9 years
    The age of son = X + 7 years
    Therefore, X + 7 = (3 X – 9)/2
    2 (X + 7) = 3 X – 9
    2 X + 14 = 3 X – 9
    2 X – 3 X = – 9 – 14
    – X = – 23
    X = 23
    Then, the age of mother = 3 X – 9 = 23 x 3 – 9
    = 69 – 9
    = 60 years
    Hence, the age of  mother is 60 years.
