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

Answer: A

Let P age and Q age is \(6x\) years and \(7x\) years respectively

Then, \(7x-6x=4\)

\(\Rightarrow\) \(x=4\)

So required ratio will be \((6x+4): (7x+4)\)

\(\Rightarrow\) \(28:32\)

\(\Rightarrow 7:8\)
