3 year ago the age of mother is 4 time of her daughter of that
time. Then find their present ages.​

Answer 1

Answer:

Sum of ages = 50.

let mothers age be x

and daughters age (50-x)

After 20 years:

Mothers age x + 20

Daughters age (50 - x) + 20

given mothers age = 2× daughters age

x + 20 = 2 (50 - x + 20)

x + 20 = 100 - 2x + 40

3x = 120

x = 40

therefore mothers age 40 yrs. Daughters age 10 yrs.
