Answer:

Let the present ages of Rahul and Haroon be 5x years and 7x years respectively.

according to condition, (5x+4)+(7x+4)=56

\Rightarrow\ 12x+8=56⇒ 12x+8=56

\Rightarrow\ 12x+8-8=56-8⇒ 12x+8−8=56−8

[Subtracting 8 from both sides]

\Rightarrow\ 12x=48⇒ 12x=48

\Rightarrow\ \frac{12x}{12}=\frac{48}{12}⇒

12

12x

=

12

48

[Dividing both sides by 12]

\Rightarrow\ x=4⇒ x=4

Hence, present age of Rahul = 5 x 4 = 20 years and present age of HAroon = 7 x 4 = 28 years
