Question

Q1. 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 ?

8 : 7

7 : 8

5 : 8

7 : 5

Accepted Answer

Answer : 7 : 8

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
