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

Let,

Rahul's age = 5x years

Haroon's age = 7x years

$<u>Four years later</u>$

Rahul's age = ( 5x + 4 ) years

Haroon's age = ( 7x + 4 ) years

A.T.Q.

5x + 4 + 7x + 4 = 56

12x + 8 = 56

12x = 56 - 8

12x = 48

x = 48 / 12

x = 4

Now,

Rahul's age = 5x = 5 ( 4 ) = $<b><u>20 years</b></u>$

Haroon's age = 7x = 7 ( 4 ) = $<b><u>28 years</b></u>$
