Answer 2

Step-by-step explanation:

Let Aril's present age is x years

Then her mother's present age is 3x years

After 5 years , Aril's age will be x+5 years

After 5 years , her mother's age will be 3x+5 years

By given condition

3x+5=3(x+5)

x=10;3x=3,10=30.

Therefore, Aril's present age is 10 years and her mother's present age is 30 years.
