Question #N834
A survey of 100 people found that 60% of them prefer brand A, 30% prefer brand B, and the rest prefer brand C. How many people prefer brand C?
A. 10
B. 30
C. 40
D. 70
Correct Answer is: A
If 60% prefer brand A, then 60 people prefer brand A (0.60 * 100 = 60). If 30% prefer brand B, then 30 people prefer brand B (0.30 * 100 = 30). Since 60 + 30 = 90, then 100 – 90 = 10 people prefer brand C.
