Question

my question no. is 9

Answer 1

let the ages be 5x and 7x
so, later 4 yrs the sum of their ages will be
5x+4+7x+4=56
12x+8=56
12x=56-8
12x=48
x=4

so, 5x=5*4=20
7x=7*4=28
ans = 20 and 28

Answer 2

Answer:

Present age of Rahul = 20 years.

Present age of Haroon = 28 years.

Step-by-step explanation:

Given that Rahul and Haroon are in the ratio of 5:7

Let the present age of Rahul = 5x.

Let the present age of Haroon = 7x.

4 years later:

⇒ Age of Rahul = 5x + 4

⇒ Age of Haroon = 7x + 4.

Given that Sum of their ages will be 56 years.

⇒ 5x + 4 + 7x + 4 = 56

⇒ 12x + 8 = 56

⇒ 12x = 48

⇒ x = 4.

Therefore:

⇒ Present age of Rahul = 20 years

⇒ Present age of Haroon = 28 years.

Hope it helps!
