Maths question

1. 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.

8. 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?

Alice says to Bill, "if you give me 1/2 of your money I'll have \$100".

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 :-)
