Question

the age of Rahul and Haroon are in the ratio 5:7 . four years later the sum of their age will be 56 years . what are their ages ?​

Answer 1

Answer:

Step-by-step explanation:

Let Rahul's age = 5x

Let Haroon's age = 7x

A/Q (5x+4)+(7x+4) = 56

5x+7x+8 = 56

12x = 48

x = 4

Rahul's age = 5x = 5x4 = 20 years

Haroon's age = 7x = 7x4 = 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
