Question #N1004
A survey of 100 people found that 60 people like apples, 40 people like oranges, and 20 people like both apples and oranges. 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 represent the information given. \begin{align*} \text{People who like only apples} &= \text{People who like apples} - \text{People who like both apples and oranges} \\ &= 60 - 20\\ &= 40 \end{align*} Therefore, 40 people like only apples.
