    So if its hypothetical...
    Bill HAD $200 and gave half to Alice, now they each have $100.
    Claire HAD $300, but gave Bill 1/3 so now Claire has $200 and Bill has $100.
    Alice HAD $400 but gave 1/4 to Claire so now Alice has $300 and Claire has $100..

    She would have $100 if Bill coughed up. It doesn't say he did though.

    The mind boggles. You've got a seriously smart kid @CMF

    Just tell him the rest was taxed. haha

    That can't end up with Bill having a hundred bucks though, he'd have two because he still has $100 after giving half to Alice.

    If it isn't a trick? ! I think I've worked it out?

    Alice has $64
    Bill has $72
    Claire has $84

    1) Alice has $64 plus half of Bill's $72 ($36) = $100
    2) Bill has $72 plus one third of Claire's $84 ($28) = $100
    3) Claire has $84 plus one quarter of Alice's $64 ($16) = $100

    Do I pass?

    Oh my gosh how did you dooooo that???
    I haven't checked the answer with him but it certainly looks right!
    Did you just guess random numbers or did you actually have a methodical way of working it out?

    Bill says to Claire, "if you give me 1/3 of your money I'll have $100".

    Claire says to Alice, "if you give me 1/4 of your money I'll have $100".

    How much money does each person have?
    I read it as if the money didn't actually move, but hypothetically if each person gave the half, third or quarter, the other person would end up with $100 - I didn't read the question as to what would happen if this occured in sequence :-)
