Question #N890
A survey of 100 people found that 60 people like apples, 50 people like oranges, and 20 people like both apples and oranges. How many people like only oranges?
A. 10
B. 20
C. 30
D. 40
Correct Answer is: C
We can use a Venn diagram to visualize the problem. The number of people who like only oranges is represented by the region of the orange circle that doesn't overlap with the apple circle. Since 20 people like both apples and oranges, and 50 people like oranges in total, then 50 – 20 = 30 people like only oranges.
