# 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 ?

$\par&space;Let&space;P's&space;age&space;and&space;Q's&space;age&space;be&space;6x&space;years&space;and&space;7x&space;years&space;respectively.$

$\par&space;Then,&space;7x&space;-&space;6x&space;=&space;4$

$x&space;=&space;4$

$\par&space;Required&space;ratio&space;=&space;(6x&space;+&space;4)&space;:&space;(7x&space;+&space;4)&space;=&space;28&space;:&space;32&space;=&space;7&space;:&space;8$
