Detailed Solution

It is given the ages of Rahul and Haroon are in the ratio 5:7.
Let the common ratio between Rahul's age and Haroon's age be x.
Then, age of Rahul and Haroon will be 5x and 7xyears respectively.
After 4 years, their ages will be (5x+4) and (7x+4)rexpectively.
According to the given condition, we have,
5x+4+7x+4=56 ⇒12x+8=56 ⇒x=4
Therefore, present age of Rahul is 5x=5×4=20 years
and present age of Haroon is 7x=7×4=28 years.
Hence, the correct option is 4.
