plz ans ​

Answer 1

Answer: The present age of Rahul is 20 years and the present age of Haroon is 28 years.

Step-by-step explanation:

Four years later the sum of their age will be 56 years.

Therefore, the sum of their present age is = {56-(4+4)} years = 48 years  

The ratio of the present age of Rahul and Haroon is 5:7

The sum of their ratio = 5+7 = 12

So, the present age of Rahul is = 5/12 of 48 years = 20 years

The present age of Haroon is = 7/12 of 48 years = 28 years  

Answer 2

Let the ages of Rahul and Haroon be 5x and 7x. Four years later,

The ages of Rahul and Haroon will be (5x + 4) and (7x + 4) respectively.

According to the question,

(5x + 4) + (7x + 4) = 56

⇒ 5x + 4 + 7x + 4 = 56

⇒ 12x + 8 = 56

⇒ 12x = 56 – 8

⇒ 12x = 48

⇒ x = 48/12

⇒ x = 4

Therefore, Present age of Rahul = 5x = 5×4 = 20

And, present age of Haroon = 7x = 7×4 = 28
