Question

30) mothers age today is thrice as her daughters. After 10 years it would be just double. How much old is the daughter today?

Answer 1

Answer:

Step-by-step explanation:

let the daughter's present age be x

Mothers age = 3x

After 10 years:

Daughters's age = x + 10

Mother's age = 3x + 10

According to the question: 3x  + 10 = 2 (x+10)

3x + 10 = 2x + 20

x = 10 years ( daughter's age)
