Question #N139

A survey asked 100 people if they liked apples, oranges, or both. The results showed that 60 people liked apples, 50 people liked oranges, and 20 people liked both. How many people liked apples but not oranges?
A. 10
B. 20
C. 40
D. 60

Correct Answer is: C

We can use a Venn diagram to solve this problem: [Venn diagram with two overlapping circles, one for apples and one for oranges. The intersection of the circles is labeled 20. The apple circle is labeled 60, and the orange circle is labeled 50. The rest of the apple circle is labeled 40, and the rest of the orange circle is labeled 30.] Since 20 people liked both, 60 - 20 = 40 people liked apples but not oranges.
