Hi AbeNeedsAnswers,
We're asked to determine how much LESS the number of students enrolled in BOTH a chemistry course and a biology course is relative to the number of students enrolled in NEITHER. The wording of this prompt implies that we're dealing with a standard Overlapping Sets question, so we can use the Overlapping Sets formula to solve it:
Total = (Group 1) + (Group 2) - Both + Neither
1) In College X there are 60 students enrolled in a chemistry course.
Fact 1 tells us one of the Groups, but nothing else.
Fact 1 is INSUFFICIENT
2) In College X there are 85 students enrolled in a biology course.
Fact 2 tells us one of the Groups, but nothing else.
Fact 2 is INSUFFICIENT
Combined, we can fill in 2 parts of the formula:
Total = (60) + (85) - Both + Neither
There's no way to determine any of the other values though.
Combined, INSUFFICIENT
Final Answer: E
