1. The ratio between the present ages of P and Q is 6 : 7. If Q is 4 years older than P, what will be the ratio of the ages of P and Q after 4 years?
- A. 3 : 4
- B. 3 : 4
- C. 3 : 4
- D. 3 : 4
Answer: Option D
Explanation:
Hints: Let P age and Q age be 6x years and 7x years
Then, 7x - 6x = 4
x = 4
So the required ratio will be (6x + 4)/(7x + 4) = 28/32 = 7/8
