Can you solve this logic Venn diagram question?
Yes, here it is. It's like before, but now "D" overlaps with "A" and "B", "A" overlaps with "B" and "C", "B" overlaps with "C" and "D", and "C" overlaps with "D" and "A". If the total number of items in all four sets is 100, what's the maximum number of items that could be in "A"?
Let me analyze this. If we start by finding the total number of items in "A", "B", "C", and "D" without overlap, we get 100/4 = 25 items in each set. However, we know that there is some overlap between the sets, so we need to adjust our calculations. Using the inclusion-exclusion principle, we can find the number of items in "A" as follows: (25 + 25 + 25 + 25) - (overlap between "A" and "B") - (overlap between "A" and "C") - (overlap between "A" and "D"). The maximum number of items in "A" would occur when all the overlap is with the other sets, not with "A". By using a similar strategy to before, we find that the maximum number of items in "A" would be 50 - (25/2) - (25/2) - (25/2), which simplifies to 25. Therefore, the maximum number of items in "A" would be 25.
