Question

The ratio of ages of Abha and her mother is 2:5. At the time of Abha's birth her mother age was 27 year. Find the present ages of Abha and her mother.

Answer 1

Let at present time age of Abha = x

at time of birth age of Abha = 0

at time of birth age of her mother = 27

when Abha will become x year's old her mother will become X+27

Thus $\frac{X}{X+27}=\frac{2}{5}$

$5X-2X=5M$

$X=18$

Abha's age = 18 yrs

Mother's age = 18+27= 45 yrs.
