By the third sentence, this is already clearly not a GMAT problem - not even close. It barely makes sense, since it isn't clear which groups are exclusive and which might overlap. It's not worth spending time on. Where is it from?

This is apparently from a collection of 770+ questions. My friend who had just given his GMAT passed me his materials and I found this unsolvable problem in it.
I am glad that such questions dont appear in the GMAT or do they?

IanStewart · Answer

No, you'd never see something quite like this on the GMAT. I've seen a lot of "800-level questions" which aren't 800-level questions at all. High level questions on the GMAT are not hard because they are extraordinarily long or complicated. They don't give you 10 equations/10 unknowns problems for example. High level problems are hard because they test several concepts in one question, cleverly disguise which concepts are being tested, require a tricky chain of logic, or include a trick or a trap that only someone with a deep understanding of the concepts will spot. I don't find real 800-level GMAT questions to be any more time-consuming than 500-level questions, at least once you see what you need to do.

Of course overlapping set questions do show up on the GMAT quite often; it's just the absurd complexity of the question in your post, and its imprecise use of language, that make it very unrealistic.
