Question

The ages of Rahul and Haroon are in the ratio 5 : 7. Four years later the sum of their ages will be 56 years. What are their present ages?

Answer 1

Answer:

Rahuls age= 20 Haroons age=28

Step-by-step explanation:

Let the common ratio between Rahul's age and Haroon's age be x.

Therefore, age of Rahul and Haroon will be 5x and 7x years 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.
