In a survey, a group of students from Westville High School were asked about their favorite movie genre. Each student in the group selected exactly one movie genre, and the data collected are summarized in the circle graph above. If 40 more students chose Action than Fiction, how many students were surveyed in total?
(A) 100
(B) 150
(C) 200
(D) 250
(E) 300
The Correct answer is D.
Explanation
From the circle graph, 30% of the students surveyed chose Action and 14% chose Fiction as their favorite movie genre. Hence 40 students is equal to 30%-14%=16% of the total number of students surveyed. Let N be the number of students surveyed; then the last statement can be written symbolically as 0.16N=40. Solving for N gives N=250. Therefore, the total number of students surveyed was 250.
