Question 1
The difference between Aubrey and Josephine's ages is 54 years. In 6 years, Aubrey's age will be 3 times Josephine's age. How old is Aubrey now?
Let Josephine = x = 21
Then Aubrey = x + 54 = 21 + 54 = 75
Check: In 6 years, Aubrey+6 = 81
3 × (Josephine+6) = 3 × 27 = 81 ✓
Then Aubrey = x + 54 = 21 + 54 = 75
Check: In 6 years, Aubrey+6 = 81
3 × (Josephine+6) = 3 × 27 = 81 ✓
