The Hardest Logic Problem In the World

3-9=6
3+3=6
not sure of the last one

8-3=5
3+3=6

Are the only two answers.

Each man payed 9 dollars for the room. There is no missing dollar.

reply to post by smithjustinb


this is right

there is no missing dollar
kid gives dollar back to each man os each man now has bayed 9
room cost 25
men end up paying 3x 9 =27
27+ 3 dollars = 30
kid gets 2
27-2 = 25
room cost 25
kid made 2 bucks off the men.

This bit is important and nullifies your answer:

The gods understand English, but will answer all questions in their own language in which the words for 'yes' and 'no' are 'da' and 'ja', in some order. You do not know which word means which."

All you have to do is translate.

It depends on whether that line is interpreted as each god defining their own 'yes' and 'no' or whether they share definitions. Even assuming the latter, your solution is incorrect. For any combination of gods, the answer will be either three yes or two yes one no (edit: or, if god no == human yes then the combinations are flipped).

If you get a yes answer first it has to be from the random God.

I agree

3-9 would equal -6 surely

This is not a question for an atheist. An atheist would argue that it's a logical fallacy to call them gods, that god doesn't exist, and that the question is a fairytale just like the rest of the religious texts of these so-called gods.

It's not a question for a monotheist either. Two of the so-called gods are not real.

You would have to ask a question in the negative. Like, "can you make a boulder than you can't lift?" Or any other snarky troll-like question, like "did you tell the Phelps' to protest that funeral?"

The hardest part is admitting that you have three gods.

Something simple like "does my butt look fat in this?" would be a decent question. Oh wait, three questions.

You find a fact about one god, making a point. Then you ask the other two about the one with the point, to rule out which ones are what. I think it can be solved with a mathematic equation even, something like calculus. I never took calculus so I have to step aside for the right answer.

BYRD,

There is a section in a text book all about truth tables to solve logic problems the book is called "A Survey Mathematics with Applications" 8th Edition by Angel Abbott and Runde


You should also check out De Morgans Laws, Euler Diagrams and syllogistic arguments. Truth tables help you solve these problems by changing words to symbols and words and statements to link them in an equation.

There isn't a dollar missing. Hotel has $25, bellboy has $2, men have $3 back = $30. Never could figure why this was considered a brain teaser. Want to play poker some time?

I've got to say - in all the years I have pondered how to explain this question, while completely understanding where all of the dollars are, this is the simplest, most succinct way to describe it to someone else. I never thought of explaining it to someone so simply. Great job and a star!

Most of the time you try to explain that the three men each paid 9 dollars and the bellboy has 2, so 9 X 3 = 27 plus 2 = 29... it makes it difficult to explain to someone that it is just a little trick.

I can find the answer in 2 questions; walk up to one of the gods...kick the god in the baby maker...Question 1: Do either of you want some? Question 2: Are you two sure?

9x3 = 27 + 2 (In the bellboys pocket) = 29. Therefor, there's a "missing" dollar.

All one has to ask is: Am i God.

And each one would reveal himself as who they are.

50% of the time the random god will answer "no".
