Question #N214
A survey of 100 students found that 60 students liked pizza, 50 students liked burgers, and 20 students liked both pizza and burgers. How many students liked only pizza?
A. 10
B. 20
C. 40
D. 60
Correct Answer is: C
We can use a Venn diagram to visualize the problem. Since 20 students liked both pizza and burgers, we subtract this number from the total number of students who liked pizza and the total number of students who liked burgers to find the number of students who liked only each food: 60 - 20 = 40 students liked only pizza and 50 - 20 = 30 students liked only burgers.
