Question #N181
A survey of 100 people found that 60 people liked apples, 50 people liked oranges, and 20 people liked both apples and oranges. How many people liked only apples?
A. 10
B. 20
C. 40
D. 60
Correct Answer is: C
We can use a Venn diagram to solve this problem. Let the number of people who liked only apples be x. The number of people who liked only oranges is 50-20=30. The total number of people in the survey is x + 20 + 30 = 100. Solving for x, we get x = 50. Therefore, 50 people liked only apples.
