To find:-
Solution:-
The ages of Rahul and Haroon are in the ratio 5:7
Let Boys present of age = 5x
Girls present of age = 7x
Four years later the sum of their ages will be 56 years. So according to the condition,
⇥ (5x+4) + (7x+4) = 56
⇥ 12x + 8 = 56
⇥ 12x = 56 - 8
⇥ 12x = 48
⇥ x = 48/12
⇥ x = 4
☘ Therefore, the present age of boys =》 5 × 4 = 20years
☘ The present age of girls =》 7 × 4 = 28years
