Let the present ages of P and Q are 4x and 5x
6 years hence the ages are 4x+6 and 5x+6 in the ratio 7 : 8

4X + 6 = 7
-------- ---
5x + 6 = 8

:- 8(4x+6) = 7(5x+6)
==> 32x + 48 = 35x + 42
==> 3x = 6
:= x = 2
The present ages of P and Q are (4*2) and (5*2) = 8 and 10
the sum of the present ages of P and Q 8 + 10 = 18 years
