Question 624668
If a mother is three times older than her daughter and in twelve years she is twice oldes than the daughter, whats the mother age now?

Solution:

Let x = Mother´s age now

Let y = Daughter´s age now

x = 3y (1)

(x+12)= 2(y+12)(2)

Then:

3y+12 = 2y+24

3y-2y = 24-12

y = 12

x = 3y =3(12)=36

Answer:  36 years
