Correct Answer: C
Explanation:
At a College, there is a total of 100 students. If 30 of the students have cars on campus, and 50 have bicycles, and 20 have both cars and bicycles, then how many students have neither a car nor a bicycle on campus?
(30 - 20) + 20 + (50 - 20) + x = 100
10 + 20 + 30 + x = 100
x = 100 - 60 = 40
