    I'll give you a hint: From the information given about the girl friends, one can deducr exactly how many girl frieds each one has, and in the variant I gave involving money instead of girl friends, one can deduce exactly how much money each one has!

    Each have four girlfriends, but one folds his girlfriends in half, thus doubling the amount :(

    Ah cute. Bob has two (twice as many as Bill which counts for one here). Bill has none, and together they have two. That is sneaky indeed, the keyword we tend to overlook is "they".

    I liked Adam's answer better as that is mathematic and does not depend on word semantics. And mine, because it is kinda funny (at least I thought that when posting :lol: )

    Joufa, there is no reason why in your solution, the number 4 should work better than any other number-- it could just as well be that each brother has ten, and one of the brothers folds five of them in half! I told you that from the information I gave, it is deducible exactly haw many each has, and there is only ONE possible solution!

    Hmmm...this is a good question. Then, with my last gasp, I would like to ask: do imaginary girlfriends count?

    Juufa, No; imaginary girl friends do NOT count!Now really; can't you think of a number such that twice the number is the same as the number itself?

    1? 1 x 1 = 1...

    That seems to work...

    Juufa, No, the number 1 doesn't work. Twice 1 is not the sam as 1X1. Twice 1 is i+i, which is 2. In general, for any number n, twice n is not nXn , but n+n. For example, twice 5 is certainly not 5X5 (which is 25), but 5+5, which is 10.

    Exactly what I was thinking. He said that doesn't work, for some reason, but as far as I know, 2x0=0. :D Perhaps there's a more clever answer that he's looking for? But I can't get past the 0, because I don't see why it doesn't work. :cry:

    Yup, last time I checked, 2x0 was still zero. But you never know with today's crazy pace of science and technology... Maybe at absolute zero temperatures, things start working differently. :lol:

    Raymond may have been referring to my first, contrived, 'solution'. IMO there is no more straightforward solution than the zero, but the latest hint seems to point in another direction (which I think I guessed after the hint).

    They had no girl friends. Twice zero is the same as zero.


    Now for a riddle: Which musical instrument is particularly intelligent?[[Answer next time.]

    Dangit, Ray! All that brain-bleeding for nothing! :lol:

    The clarinet? As in, like....clairvoyant? That's the best I can come up with at the moment. :D

    This had already been guessed, then dismissed as not correct :roll:

    I seem to have completely missed this thread!

    I'll attach something that might keep you away from the piano for a while ;). Yes, you can "brute force" your way through it but it is more fun if one think first. Download and run (you need Powerpoint installed).

    Robert - can it be solved?
