Answer»

Answer:

15 years and 45 years

Step-by-step explanation:

Present ages:

LET the age of WILSON be n.

Age of her mother =3n.

Before 5 years:

Age of Wilson=n-5

Age of her mother=3n-5. Or 4(n-5)

3n-5=4n-20

-5+20=4n-3n

15=n

n=15 years.

Age of Wilson=15 years.

Age of his mother =15*3=45 years.
