- 11 Dec '05 20:14- There are 3 boxes

- Only one of them contains gold

- Every box has a message written on it and only one message is true.

- On box 1 is written: "This box is empty"

- On box 2 is written: "Box 3 contains the gold"

- On box 3 is written: "The other boxes are empty"

Which box contains the gold? - 11 Dec '05 20:33

The message on both box 2 and 3 say that box 3 contains the gold, they both can't be write so box 3 doesn't contain the gold.*Originally posted by LordOfTheChessboard***- There are 3 boxes**

Box 1's message must be true because the other two are false. This means that box 1 doesn't contain gold, neither does box 3.

Thus box 2 must contain the gold. - 11 Dec '05 21:28

It could be box 3, if box one contains a rock or something.*Originally posted by LordOfTheChessboard***- There are 3 boxes**

Or it could be box 2. There's not enough information to tell which. - 11 Dec '05 21:34 / 1 edit

That's true. I think you have to assume that each box can only contain either gold or nothing at all, in which case the labels point to box 2 as containing the gold.*Originally posted by iamatiger***It could be box 3, if box one contains a rock or something.**

If there is a rock in box 1 and the gold is in box 3, how many messages are true? - 13 Dec '05 14:16Read carefully:

box 1 contains a ROCK, this has not been excluded by the original question.

Box 3 Contains the GOLD

On box 1 is written: "This box is empty" FALSE - There is a rock in it

On box 2 is written: "Box 3 contains the gold" TRUE - It does

On box 3 is written: "The other boxes are empty" FALSE - There is a rock in box one

Hence 1 true statement, therefore box 3 could contain the gold.

Sorry about the Caps, getting a bit too excited.
