Logic Puzzles from multiple points of view 3/5

July 2, 2009 am31 7:41 am

Over the next few days I’ll be posting a group of five puzzles, related by a “multiple points of view” theme.

None of these puzzles belong to me. And I don’t know where to extend credit. I think they’ve just sort of existed, forever.

Perfectly Logical Pirates

Logical Pirates enjoy (in this order):
1.  staying alive,
2.  getting lots of loot, and
3.  killing other pirates.

Five Logical Pirates come upon a treasure chest of 100 indivisible gold coins.

They agree to draw lots and establish an order (A, B, C, D, and E) and that then each pirate in turn, starting with A, must suggest how to split the loot and all (living) pirates, including the proposer, will vote on it. If a suggestion gets a majority vote, they split the gold according to that suggestion and go home.  If a suggestion fails to receive a majority vote (a tie loses), the proposer is killed, and the next pirate makes his suggestion.

Pirate A steps up

  • I suggest that the gold be divided in the following way:  ___________ ______________ __________ __________ _____

What does he suggest? Explain why it is his best suggestion.

Place questions/clarifications below. To submit proposed solutions, click here.

    If a proposal gets an equal number of ‘yay’ and ‘nay’ votes, is it accepted or rejected?

    a tie loses, the proposer is killed.

    The proposer himself has a vote.

    Nice post. That was very informative!! I hadn’t heard all of that before, so I don’t really know what to say lol. Anyway, I like your site a lot. I’ve been skimming around, and I like what I see. Nice layout too. ;)

    Jeff,

    thanks for the wikipedia link. I will add the SciAm and Ian Stewart references.

    The article solves a slightly more common variant of the puzzle – so the answer is a bit off for the puzzle here, as presented.

    Also, people like to solve puzzles in this space; I’m going to hide your answer.
