Comment on 20 Students - Question II
Can you clarify this again
I can certainly try to clear
I can certainly try to clear up any confusion. Can you tell me what part of the solution you are having problems with?
Here although answer is 6/12
Any fraction that's
Any fraction that's equivalent to 1/2 would be considered correct.
The only condition is that the numerator and denominator must be integers.
So, all of the following would be deemed correct: 3/6, 1/2. 6/12, 100/200, etc

Do you think that this question can be solved using the above-mentioned matrix?
Thanks,
Ketan

While many/most GRE data
While many/most GRE data interpretation questions involve familiar graphs and charts, the test-makers aren't immune from also providing non-standard diagrams in their questions. Consider, for example, this official question: https://gre.myprepclub.com/forum/if-the-ceilings-and-walls-of-the-living...
It's also worth noting that on page 319 of the Official Guide to the GRE General test (3rd edition), we're provided with a Venn diagram from which we must make certain conclusions: https://imgur.com/mHMGFvn
