At a certain university the ratio of the number of teaching assistants to the number of students in any course must always be greater than 3:80. At this university, what is the maximum number of students possible in a course that has 5 teaching assistants ?
Tricky. I'll go with (D).
3 : 80 = 5 : 133.3
The closest maximum ratio (among the options provided) greater than 5:133.3 is 5:133. Hence (D)
