Question

A woman is 3 times as old as his daughter. After 9 years, the mother will be 2 times as old as the daughter. How old is mother now?

Answer 1

Answer: Mother is 27 years old now.

Explanation:

Use x as a substitute.

Mother = 3x Daughter = x

In 9 years : Mother = 3x + 9 Daughter = x + 9

It is given that the mother will be 2 times as old as the daughter.

3x + 9 = 2 (x + 9)

3x + 9 = 2x + 18

- 9

3x = 2x +9

-2x

x = 9

So, now, 3x will equal 3(9) = 27

Mother is 27 years old.
