The ratio of the ages of neeti & yash is 4 : 3, the sum of their ages is 28 yrs. what is the ratio of their ages after eight years?

Let neeti age=n

and yash age = y

then n/y = 4/3

so n=4y/3

similarly

n+y=28

putting value of n

4y/3+y=28

(4y+3y) / 3=28

7y/3=28

y=28*3/7

y=4*3=12

so y=12

n=4y/3

n=4*12/3

n=4*4=16

so ages

yash=12

neeti=16

after 8 years

yash=12+8=20

neeti=16+8=24

neeti/yash = 24/20

neeti/yash = 6/5
