    Solution

    ATQ,

    Let the present age of the son and the father be 'x' years and '5x' years, respectively.

    Then, present age of the mother = (5x - 5) years

    So, x + 5x + (5x - 5) = 110

    Or, 11x - 5 = 110

    So, x = (110 + 5) Ă· 11 = 10

    Present ages of the son and father are 10 years and 50 years, respectively.

    For some 'y',

    (10 + y) Ă— 2 = (50 + y)

    Or, 20 + 2y = 50 + y

    So, y = 30

    30 years hence from now, the father will be twice as old as the son
