If you're bored, try to solve this puzzle. I'll be impressed if anyone on LetsRun can actually do it.
Since we know all of you have IQs of 140+, now is the time to prove it.

Are you trying to have someone do your homework for you?
Solution found!
Took me about a minute
I'm not in school anymore. I went through an entire book of logic puzzles for fun and this was the most difficult one. The answer is in the back of the book along with one way to arrive at that solution so this is just to see if anyone on LRC can do it.
More a matter of if anyone wants to do it, than if anyone can.
Why did they start two of the women's names with the same letter? Who wrote this problem - Tolkien!? What a dick.
This is a really really common theme in logic puzzles. Set up a grid, plug in the Xs and Os and you'll have your answer.

That won't get you very far with this problem. I mean you can set up a grid but it really won't help you very much. You're going to need to do a lot of proof by contradiction. You'd need the working memory of a god to solve it without writing down your assumptions and the contradictions they imply.
Also note that you're not given the values for the points.
To get around names I usually just label people as "P1, P2" and dishes as "D1, D2" and so on. I use a gender sign to keep track of gender.
FWIW this is from a Dell Logic Puzzles book, and grids are pretty much only useful for one star, two star, three star, and a handful of four star problems. Once you get to five star problems they're not going to help you at all most of the time, so they don't even bother printing grids in the book.
Find the answer? I suggest we "Go to the Food network video tape!"
This is a standard multi-grid puzzle, they all take 5-15 minutes to solve depending on your skill level.

You're not given enough information to solve it without many long proofs by contradiction. If you don't believe me, try it. If you can solve it in fifteen minutes I will be very impressed. I can solve all the one two three and four star puzzles in that time period and this took me much longer.

This ^.
Seriously, how could anyone think that it would be particularly difficult?
xenon, I am surprised and disappointed with you.

lol if it only takes 15 minutes then surely it's not a big deal to just get it done quickly and move on with your life
Of course it takes more than 15 minutes. But it is more tedious than challenging. Much like a 6-star sudoku, where you have to start guessing and eliminate the wrong guesses.
I have no experience with any logic problems and tried this out, I thought I had it almost done after so much tedious work but I ended up getting screwed because I made a mistake somewhere early on. This is definitely difficult.

Suit yourself. The excitement of hunting for the right assumptions to make to lead to contradictions which give me the most information is fun to me. It's part of why I majored in math. It's really exciting when you finally make a breakthrough.

No, I'm disappointed with LetsRun. How did we go from accurately predicting Mo Farah's marathon potential to the tenth of a second to not even being able to make headway on this?
I wonder if I am the only poster here who has actually had a logic puzzle published (Penny Press). They gave me $35 back in like 2001, 2002.
I've give this sucker a shot.

Now this is more like the type of response I would expected here. LRC are the influencers of the world, not just the influenced.
