help w/this logic problem please...
Tom, Dick and Harry have been friends for many years. One is a habitual liar, one always tells the truth, and one sometimes lies. One of them dropped a $10 bill and it landed at their feet.
Tom says: "The $10 is mine." Dick says: "Tom is telling the truth." Harry says: "It belongs to Dick." Whose $10 is it? THis is probably really simple... but I'm just not seeing it. Does anyone have an idea?

isn't this suppose to be in the tilted knowledge? no matter. i don't know the answer, but we can start by trying out a few situations.
First: if the $10 were Tom's then Tom would be telling the truth, Dick would also be and Harry would be the lier. I don't see anything wrong with that Second: if the $10 were Dick's then Tom would be lying and Dick also would be and Harry is telling the truth. Dunno, right now it seems both situations work. i'll need to think about it more |

This one seems to work:

Maybe some more match, but if you replace knight with truth-teller, knave with liar, and sometimes with normal, you should get your answer. |

Let's see if I've done this right:
Normal = $10 Tommy - I'm normal ($10 is mine) --> Tom Babbette - That's true ($10 is Tom's) --> Dick Cathy - I'm not normal ($10 belongs to Dick, not me) --> Harry Harry (Cathy) is the Knight --> always tells the truth Since Harry always tells the truth and states the $10 is Dick's, then... the $10 belongs to Dick. |

the first time i looked at it i got the $10 being Dicks,
Tom says: "The $10 is mine." ---> sometimes lies Dick says: "Tom is telling the truth."--> always lies Harry says: "It belongs to Dick."-->never lies seems to work...

There are only 3 possibilities...
1) The $10 is Tom's: Tom tells the truth, Dick tells the truth, Harry lies 2) The $10 is Dick's: Tom lies, Dick lies, Harry tells the truth 3) The $10 is Harry's: Tom lies, Dick lies, Harry lies Clearly 3) can't be correct, but technically both 1) and 2) are acceptable options. 1) makes more sense than 2) if you consider how people would be likely to react in the situation. |

Very true, so it can't be Harry's cause then they would ALL be lying... thanks for that idea.
ok so possible conclusions: the $10 is Dicks- Tom and Dick are liars and Harry tells the truth The $10 is Tom's- Then Tom would be telling the truth, Harry is the liar, and Dick sometimes lies (but is telling the truth now). how am i suppose to know which one the answer is... they both seem to work

As far as I can see, there are two possibilities, philanthropic and misanthropic. We can either believe the truth prevails and the dollar is Tom's, or that liars are everywhere and the dollar is Dick's.
Or as an alternate approach to option 2 from a lighter perspective on humanity. Tom is having trouble making ends meet. As he and his friends are walking down the street, one of them drops a ten dollar bill. Tom, desparate for cash and a habitual liar, claims the money as his. Dick knows of Tom's plight and although he's a decent person, he occasionally tells a fib and corroborate's Tom's claim in order to help him without it seeming like charity. Harry is unaware of Tom's financial problems and, always the truth-teller, correctly asserts that the bill is Dick's, but is quickly elbowed in the ribs by Dick and Tom is allowed his small windfall to go towards last month's rent.... wow I can't believe I came up with that bullshit.

It has to be Tom's. If Harry was the truthteller, and the money was in fact Dick,s then why the heck would Dick say it was Tom's?? He would claim his own money! So there for, Harry is lying, and either Tom or Dick is telling the truth. Regardless of which one is being truthful- they are both saying the money is Tom's. Therefore all signs point to>>>>>> TOM!

thanks for all of your help with this quetsion... it turned out that my Professor left out a line!! It made me crazy when she told us that! haha
Ok so without the last line there were multiple answers.. it could have been tom's or dick's but the last line of the question is: If the $10 belongs to a liar then who's is it? so then the answer is: It's Dick's $10
