ITT post puzzles/riddles and solve them

I'll start with this one

Re: The Puzzle Thread
 

41 or 11? :)

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.

Re: The Puzzle Thread
 

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
 

a man walks into a bar. how expensive was his medical bill in america?

Re: The Puzzle Thread
 

no, owa got the answer i'm p-sure. have heard that riddle before.

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

Re: The Puzzle Thread
 

nope, wrong.

Re: The Puzzle Thread
 

says on the puzzle page that had the image

Re: The Puzzle Thread
 

I'm curious, is there another solution or are you just being lito

leonid post more number shit, noname sniped too quickly

Re: The Puzzle Thread
 

If you choose one among the following, what is the probability that you get the correct answer?

A. 25%
B. 50%
C. 60%
D. 25%

--------

A well known facebook prank, but it actually has a solution

Re: The Puzzle Thread
 

Probably 0% since the answer itself doesn't have to be confined to those 4 choices.
Unless I'm interpreting something wrong.

Re: The Puzzle Thread
 

ya that's what I was thinking as well, if it's not 0% then im curious to see what the answer is

Re: The Puzzle Thread
 

Provide simple mathematical explanation for bonus points

Re: The Puzzle Thread
 

The answer is in this post, be careful if you want to solve it yourself.

Re: The Puzzle Thread
 

Can't do math l0l
I'll add onto this post, but for now, here's some rambling.

Even if the choices were different (e.g. a) 10% b) 20% c) 30% d) 40%), it wouldn't change the question. Unless the correct answer is one of the choices, there's no way to pick the right answer from the given choices. In this case, assuming uniform distribution, the answers will be weighted with different probabilities. Because of this, the answer changes depending on the which choice you pick. I'm trying to think of a mathematical approach but nothing's coming up at the moment.

hint pls
