<h3><u>Question</u><u>:</u></h3>
Emily is 4 times as old as Tiffany. In ten years time, Emily will be twice as old as Tiffany. Find their ages.
<h3><u>Solution</u><u>:</u></h3>
- 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.
<h3><u>Answer:</u></h3>
Emily's age is 20 years and Tiffany's age is 5 years.
