Re: The Puzzle Thread

I see you went for the shifting x*y+z / x*y-z pattern.

Unfortunately this doesn't fit the third triangle. I might be missing something obvious, however.

Although if you choose to go along with that pattern, there are some other low-hanging solutions that might be valid.

Re: The Puzzle Thread

x = highest number
y = middle number
z = lowest number

x*y - z*z

Answer is 29

Re: The Puzzle Thread

x = 6
y = 5
z = 1

Too bad, didn't solve it using simplex, just guessed it.

noname219's post was the solution, not a new puzzle.

I was thinking too deep into the puzzle and thought it had something to do with volume of a prism


Edit: Here's a really common riddle.

Shown above are four men buried up to their necks in the ground. They cannot move, so they can only look forward. Between A and B is a brick wall which cannot be seen through.
They all know that between them they are wearing four hats--two black and two white--but they do not know what color they are wearing. Each of them know where the other three men are buried.
In order to avoid being shot, one of them must call out to the executioner the color of their hat. If they get it wrong, everyone will be shot. They are not allowed to talk to each other and have 10 minutes to fathom it out.
After one minute, one of them calls out.
Question: Which one of them calls out? Why is he 100% certain of the color of his hat?

Re: The Puzzle Thread

Assuming D can see both B and C, C knows his hat color on the basis that D hasn't claimed his own as black from seeing two whites in front of him.

If D can only see C, then idk.

Re: The Puzzle Thread

oops i guess d can see c and b

edit- also the thing about the aforementioned riddle: assume each individual has high cognitive and intellectual sense and that none of themselves are retarded

Re: The Puzzle Thread

[One Winged Angel]

Re: The Puzzle Thread

if D can only see C, C can only see B, and A and B can't see shit, I'm pretty sure they all die unless they guess correctly

[Litodude]

Re: The Puzzle Thread

nope, wrong.

[leonid]

Re: The Puzzle Thread

nope, wrong.

A & B can only see their respective sides of the wall, C can see B, and D can see B & C.

says on the puzzle page that had the image
