Question

the ratio between the percent ages of jyoti and am it is 8:9 resp.after 4 years jyoties age Will be 28 year.what was the amits age 8 yr ago​

Answer 1

Answer:

let their ages be 8x and 9x

after four years their ages will be

8x +4 and 9x+4

8x+4=28................(given)

8x =28-4

x=24/8

x=3

substituting value of x in 9x to find present age of am

=9×3

=27 years is the present age of am

we need to find am age before 8 years

his present age -8 years ago

=27-8

=19 years

therefore ams age before 8 years was 19 years
