Ages — present ratio then future double condition: At present Palash is three times Arnav. After 7 years Palash will be twice Arnav. After another 14 years from that point, what multiple of Arnav’s age will Palash’s age be?

Difficulty: Easy

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
