Conundrum: 7, 8, 9, Venn!

Tuesday, May 1st, 2007

In a Venn Diagram puzzle, there are three overlapping circles, marked A, B, and C. Each circle has a different rule about who or what can go inside. The challenge is to guess the rule for each circle. You can find a more detailed explanation of Venn Diagram puzzles, along with an example, here.

You’ve told me that there’s not enough math on this site, and I have listened. Each of the eight items below is a number.

Have you figured out one of the rules? Two? All three? Feel free to post whatever you’ve got in the comments below. Just tell us which circle you’re solving, and what the rule is.

Enjoy!

UPDATE: Circles B and C solved by Kenneth W. Davis. See comments for all answers.
