Question

Q100. Sum of present ages of P & Q = 64 years. Sum of present ages of R & Q = 56 years. Ratio of age of P after 12 years to age of Q six years ago = 4:X. Age of R after 12 years = 32 years. Find X.

1. A. 1
2. B. 5
3. C. 3 (Correct answer)
4. D. 7
5. E. 9

Correct Answer

Option C — 3

Detailed Solution & Explanation

The correct answer is 3.

Key Points

• R after 12 = 32 → R now = 20. Q = 56–20 = 36. P = 64–36 = 28. P after 12 = 40. Q 6 years ago = 30. Ratio = 40:30 = 4:3 → X = 3.
