  1. @mmiguel, Nice.
  2. @rocdocmac, Challenging puzzle! Clearly you spent some time on it. @Thalia, your questions (and the answers) were helpful. BTW, are you giving up on the puzzle? Have you listed all items by category yet? I'm in that process now, as a first step, before making a grid. Comments Assumptions: (just mention the ones that might be wrong) Questions:
  3. Eight young people met at a party. After the revelry, each had fallen in love with one of the four persons of opposite gender and came to be loved by another of those four. Here are the particulars. John fell in love with a girl who is, unfortunately, in love with Jim. Arthur loves a girl who loves the man who loves Ellen. Mary is loved by the man who is loved by the girl who loved by Bruce. Gloria hates Bruce and is hated by the man who is loved by Hazel. So ... Who loves Arthur?
  4. Both good answers. Here's another.
  5. For convenience I'll post the puzzle here in text form.
  6. Certainly. Let me know if you have any difficulty.
  7. Can you find irrational numbers a and b such that ab is a rational number?
  8. Agree. When I hit the send button, I realized my thinking was too simple. But instead of deleting my post (moderator privilege) I left it to take its licks.
  9. I agree. I put it into his post.
  10. You are correct. But where shall the cut be positioned? Probably four. One for each side
  11. Good question. Not similar. Not congruent. Just equal area (viewed from top) any shape.
  12. Meanderings.
