Question

The age of shirish and kunder are in the ratio of 5:6.after 8 year the ratio off their ages will be 7:8. what is the difference in their ages

Answer 1

let x prepare in the ratio then 5x by 6x .

5x +8 \6x +8 =7\8
8( 5x +8) = 7( 6x +8)
40x +64 = 42x +56
42x -40x = 64 - 56
2x= 8
x = 4
present age of shirish is 20 year.
present age of kinder is 24 year.
difference of their ages
24 - 20 =4 year .

then,kinder is four year grater than shirish.

Answer 2

Answer:

The difference in their ages is 4 years.

Step-by-step explanation:

Given: Age of Shirish and Kunder are in the ratio of 5:6 & after 8 years the ratio of their ages will be 7:8.

To find the difference in their ages.

Let Shirish & kunder's age be 5x & 6x respectively.

After 8 years:

(5x+8)/(6x+8)=7/8

40x+64=42x+56

        2x=8

          x=4

So, Shirish's age=20 years

And Kunder's age=24 years.

Difference between their ages= (24-20) years

                                                  =4 years.
