Please share a video for 3 Venn diagrams. Also, kindly discuss two different types of formulae used to solve the 3 Venn diagram i.e. when we know the number of items in each circles and combined areas, and when we don't know the same.
Hi Abhiyan, 3 criteria venn diagrams are much rarer, but they use all the same concepts as normal 2 criteria venn diagrams. For more information, though, you'll want out check out this post that goes into more detail! magoosh.com/gmat/gmat-sets-venn-diagrams/
I think an easier way to solve this is to look closely at that 90%. we know that 90%, or 90 individuals, are academic professors or tenured or both, so the other 10 individuals must be professional professors non tenured. remembering that there are 40 professional professors, then 30 of those 40 are tenured, and there you have your answer
The sentence tells us that 90% of the professors are academic or tenured or both. So, the question asks us to find what percent of the professors who are professional are tenured. Hope that helps!
Great video and a nice problem. Your videos are always helpful

Very helpful!
Thank you!
I dont find these questions after working on them hard, however organizing the information is the hardest part.
Thanks a lot Erika n magoosh
So you can use a (3x3)/triple matrix instead of 3 Venn diagrams for 3 overlapping sets and so forward?
Check out minutes 9-10 in the video where Erika discusses this!

Hard to figure out what the 90% sentence means
