Doesn't option C also resolve the paradox.

Over the last 4 years, 14000 students have participated in the survey. Let's say 2k in year 1, 3k in year 2, 4k in year 3 and 5k in year 5. suppose in year 1, total 500 out of 2000 cheat on exams and in year 4, total 1000 out of 5000 cheat on exams. So, the number of cheaters has increased, but the percentage of cheaters has actually decreased.

Please help regarding my doubt.


The first sentence states that all 14,000 students were surveyed. The survey was not conducted "over the last 4 years", but the percentage has decreased "over the last 4 years" - each year all 14,000 students were surveyed. There is a small assumption leap here, but it is less practical to assume that the survey was carried out over 4 years to cover 14,000 students - after all why would a University do that as that would not give it any useful data to compare with each other - than to assume that all 14,000 students were surveyed every year.

Okay, now i get why C is wrong. Got confused because of the wordings in the stimulus.
Thank you.

hello, I cannot find the original source of this question.
Also, the question contains patterns that are much different from any patterns in official gmat questions. For example, D is OA in one question from OG. Therefore, I hardly believe the question is a gmat-like question.
