Question #N635
A survey of 100 people found that 60% of them prefer apples, 30% prefer oranges, and 10% prefer bananas. If 20 more people are surveyed, and the same percentages of people prefer each fruit, how many of the 120 people surveyed would prefer oranges?
A. 24
B. 30
C. 36
D. 42
Correct Answer is: C
Since 30% of the 100 people surveyed prefer oranges, 30 people prefer oranges. If the same percentage of people prefer oranges out of 120 people, then 30% of 120 people prefer oranges. 30% of 120 is 0.30 * 120 = 36.
