Question #N165

A survey of 100 people asked them whether they preferred apples or oranges. Of the people surveyed, 60% said they preferred apples. How many people preferred oranges?
A. 10
B. 20
C. 40
D. 60

Correct Answer is: C

If 60% of the 100 people surveyed preferred apples, then 100 - 60 = 40% preferred oranges. Since 40% of 100 is (0.40)(100) = 40, then 40 people preferred oranges.
