Question

The ratio between the present ages of P and Q is 6:7. If Q is 4 years old than P, what will be the ratio of the ages of P and Q after 4 years

  • A) 7:8
  • B) 9:8
  • C) 3:8
  • D) 5:8
Solution

Answer: Option A

Explanation:

Let P age and Q age is 6x years and 7x years.
Then 7x - 6x = 4 <=> x = 4

So required ratio will be (6x+4): (7x+4) => 28:32 => 7:8

Answer: Option A

Explanation:

Let P age and Q age is 6x years and 7x years.
