Dear Student ,

$L e t t h e p r e s e n t a g e o f R a h u l b e 5 x y e a r s . L e t t h e p r e s e n t a g e o f H a r o o n b e 7 x y e a r s . A f t e r 4 y e a r s, A g e o f R a h u l = (5 x + 4) y e a r s A g e o f H a r o o n = (7 x + 4) y e a r s T h e s u m o f t h e i r a g e s a f t e r 4 y e a r s i s 56 . ∴ (5 x + 4) + (7 x + 4) = 56 ∴ 5 x + 4 + 7 x + 4 = 56 ∴ 12 x + 8 = 56 ∴ 12 x = 56 - 8 ∴ 12 x = 48 ∴ x = 48 / 12 ∴ x = 4 ∴ P r e s e n t a g e o f R a h u l = 5 x = 5 (4) = 20 y e a r s P r e s e n t a g e o f H a r o o n = 7 x = 7 (4) = 28 y e a r s T h u s, t h e p r e s e n t a g e o f R a h u l i s 20 y e a r s w h i l e t h e p r e s e n t a g e o f H a r o o n i s 28 y e a r s .$
