Quantity I: A's age is 5 times his son's age. After 15 years, the ratio of A's age to his son's age will be 13:5. Find A's age (in years). Quantity II: 45 What is the relationship between Quantity I and Quantity II?
- Quantity I > Quantity II
- Quantity I < Quantity II
- Quantity I ≥ Quantity II
- Quantity I ≤ Quantity II
Correct answer: Quantity I > Quantity II
Solution
Let the son's present age be x, so A's present age is 5x. After 15 years, \(\frac{5x+15}{x+15}=\frac{13}{5}\). Solving gives x = 5, so A's age is 25 years. Since 25 < 45, Quantity I is less than Quantity II.
