The ratio of age of abha and her mother is 2 : 5 at the time of abha's birth her mother age was 27 year.find the persent ages of Abha and her mother

Answer 1

abha age= 2x
mother age=5x
mother-abha=27
5x-2x=27
x=9
abha age is 18
mother age is 45

Answer 2

$\frac{abha}{mother} = \frac{2}{5}$
let abha age= x
her mothers age = x+ 27


$\frac{x}{x + 27} = \frac{2}{5}$
5x = 2(x+27)
5x = 2x + 54
3x =54
x= 54/3
x= 18 years
