Answer 1

Answer:

hii mate your solution is here:::---

Step-by-step explanation:

Let the common ratio of their ages be x

Let the Hari's age be 5x and Harry's age be 7x

Five years later:-

Hari's age=5x+4

Harry's age=7x+4

According to question....

5x+5 = 3

7x+5    4

By cross-multiplication,We get,

4(5x+5)=3(7x+5)

20x+20=21x+15

20-15=21x-20x

5=x

x=5

Present age of Hari=5x=5×5=25 years

Present age of Harry=7x=7×5=35 years
