Question: 552

9. Eighty students went on a class trip. If there were 14 more boys than girls on the trip, how many girls were on the trip?

A. 26
B. 33
C. 40
D. 47
E. 66

Correct Answer: B


B This is a great problem to solve with Plugging In The Answers. Let's start with C. Could the number of girls on the trip be 40? If there are 14 more boys than girls, then there must be 40 + 14 = 54 boys. But that makes a total of 94 students; that's too much because there are only 80 students. So you can cross off C, D, and E because they are all too big. Let's try B. Could there be 33 girls? In this case there will be 33 + 14 = 47 boys, and 33 + 47 equals 80. So B is the answer.
