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 \((6x+4): (7x+4)\)
\(\Rightarrow\) \(28:32\)
\(\Rightarrow 7:8\)
