5 years ago, Paula was 3 times as old as Karl. In 6 years, Paula will be twice as old as Karl. What is the sum of their ages now?
Choose the correct choice from the following:
A) 42
B) 46
C) 50
D) 54
E) 58
P-5 = 3(K-5) and so P = 3K-10   P+6 = 2(K+6)   (3K-10)+6 = 2K+12   K = 16   P = 38   P+K = 54   The answer is 54.
