Question 1

10 years ago, A was half as old as B. In 5 years, what will be the age difference between B and A?
10 years ago: A was 15, B was 20. Check: 15 = ½ × 20 ✓
Present ages: A = 25, B = 30
In 5 years: A = 30, B = 35
Age difference = |35 - 30| = 5
(Age difference stays constant over time = B - A = 5)

Question 2

10 years ago, A was half as old as B. In 5 years, what will be the age difference between B and A?
