Answer
Correct Answer: 1.5
Explanation
Introduction / Context:We are given a present multiple and a future “twice” relation after 7 years, then asked about a further 14-year shift. Solve current ages first, then project forward.
Given Data / Assumptions:
- P = 3A now.
- P + 7 = 2(A + 7).
- Question asks for the ratio P : A after an additional 14 years from that future point (i.e., 21 years from now).
Concept / Approach:Find A and P now, then add 21 years to each and compute the ratio.
Step-by-Step Solution:
3A + 7 = 2A + 14 ⇒ A = 7.P = 3A = 21.In 21 years: A = 28, P = 42 ⇒ ratio = 42 / 28 = 1.5.Verification / Alternative check:
After 7 years: 28 vs 14 ⇒ P is twice A ✓Why Other Options Are Wrong:
- 1, 3, 2 do not match the computed projection.
Common Pitfalls:
- Projecting only 14 years from now instead of 21 years total.
Final Answer:1.5
