Question:

Emily is 4 times as old as Tiffany. In ten years time, Emily will be twice as old as Tiffany. Find their ages.

Solution:Let the age of Tiffany be x years.Then, the age of Emily = 4x years.After 10 years, the age of Tiffany will be (x+10) years.After 10 years, the age of Emily will be (4x+10) years.Therefore, by the problem

So, Tiffany's present age = 5 years.Emily's present age = (4×5) years = 20 years.

Emily's age is 20 years and Tiffany's age is 5 years.

Hope it helps!
