Question #N466
A survey of 100 people found that 60 people like apples, 40 people like bananas, and 20 people like both apples and bananas. How many people like only apples?
A. 20
B. 40
C. 60
D. 80
Correct Answer is: A
We can use a Venn diagram to solve this problem. Draw two overlapping circles, one for apples and one for bananas. The overlap represents the people who like both. Since 20 people like both, we write 20 in the overlap. Since 60 people like apples, we write 40 in the apple-only part of the apple circle. Therefore, 40 people like only apples.
