      Solution

      ATQ,

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

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

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

      So, 5x = 24

      Or, x = 24/5

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