Eight years ago, the ratio of ages of P and Q was 5:2. Six years from now, the ratio of their ages will be 4:3. What is P's age at present? Choose the correct choice from the following answers
A) 16 B) 18 C) 20 D) 22 E) 24
2(P-8)/5 = (Q-8). Then Q = 2(P-8)/5 + 8   3(P+6)/4 = Q+6   3(P+6)/4 = 2(P-8)/5 +14   15P+90 = 8P + 216   7P = 126   P = 18   The answer is 18.
