    Solution

    ATQ,

    Let the present age of Aman and Dinesh be '2x' years and '3x' years, respectively.

    So, present age of Rohan = 5/3 × 3x = 5x years

    Rohan's present age = (20 + 4) = 24 years.

    So, 5x = 24

    Or, x = 24/5

    Required sum = (2x + 3x) = (5x) = (5 × 24/5 ) = 24 years
