Ratio of present age of P and Q is 7 : 3. After four years their ages are in the ratio of 2 : 1. What is the present age of P ?	Pick.
A) 24 years
B) 28 years
C) 32 years
D) Data inadequate
E) None of these
P⁄Q = 7⁄3 ⇒ Q = 3⁄7P.....(i)   also,2Q + 8 = P + 4   or, 2Q – P = – 4...(ii)   Combining equations (i) and (ii), we get   P = 28 years   Answer 28 years
