Question: 630
3. Kenny is 5 years older than Greg. In 5 years, Kenny will be twice as old as Greg is now. How old is Kenny now?
- A. 5
- B. 10
- C. 15
- D. 25
Correct Answer: C
Explanation:
The question is asking for a specific value and there are real numbers in the choices, so use PITA to solve, starting with (C). The choices represent Kenny's age now. If Kenny is 15 years old and he is 5 years older than Greg, then Greg must be 10. In 5 years, Kenny will be 20. Twice as old as Greg is now would be 2(10) = 20. Since the two numbers match, stop here. The correct answer is (C).
