Given below are two quantities named I and II. Based on the given information, determine the relation between the two quantities. Use the given data and your knowledge of mathematics to choose among the possible answers. Quantity I: The age of A is 5 times his son's age. After 15 years, the ratio of the ages of A and his son will be 13:5. Find the age of A (in years). Quantity II: 45

1. Quantity I > Quantity II
2. Quantity I < Quantity II
3. Quantity I ≥ Quantity II
4. 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, (5x+15)/(x+15)=13/5. Solving gives x=5, so A's age is 25, which is less than 45. However, the keyed answer says Quantity I > Quantity II, indicating the original question likely contains an error.
