Hi Rudy,
That's a fun one. I remember working it out a few different times.
Last time was a couple years ago.
As I recall I believe it was one of Einstein's favorite puzzles.
On a related note ----
Does anybody know the *exact* wording for the 'Holmes/Moriarity' puzzle?
I've been looking for it for a while now ... No luck ;-(
It goes *something* like this:
A neutral third party gives the sum of two integers (each less than 40)
to one of them (Moriarity I think) and the product of the two numbers to
the other.
They meet later in a bar.
Moriarity says "I don't know what the numbers are."
Holmes says "Well I don't know either."
Moriarity says "Well I still don't know what the numbers are."
Holmes says "Well I don't know what they are either."
Moriarity smiles smugly and says "Well! I do know what the numbers
are."
Holmes turns beat red, grimaces angrily, then says "Well I do too!" and
quickly finished his pint.
The question is, of course, what were the numbers.
The first time I saw the puzzle I thought it was an April fool joke
because it's sooooo obviously impossible to solve.
The second time I saw it was in an MAA [1] publication, so I knew there
_had_ to be a solution.
... so I solved it.
But I'd really like to find the correct wording of the puzzle.
Anybody?
