Step-by-step explanation:
let the age be X and the present years from her birth be y
hence,27+y=5x. _(1)
0+y=2x. _(2)
on substracting equation 2 from 1 we get,
(27+y =5x)-(0+y=2x)
27=3x
X=9
therefore the present age of abba is 2x =2×9
18 years
and the present age of her mother is 5x =5×9
45 years

It's given that at the time of Abha's birth, her mother's age was 27 years. So here we need to subtract both the values (ratio of Abha and her mother's age) and find the value of x.
