Well thought out. keep it up
Unless I'm missing something, this teaser doesn't work. Mitch is supposed to have 6 times as many nickels as Rebecca, but he has 11 to her 2. It wouldn't work if he had 12 nickels, anyway. I don't think that there is a solution to this one. Anybody else find one?
I agree with Bobort.........very illogical.
You're right, I missed that!
This doesn't work because of the constraint on Mitch (6x number of nickels than Rebecca).

in my country 2 x 6 = 12, but this must be one of those quaint ways of doing things they have over in UK.
Is twist from UK? strang, I thought if that weer the case the teaser would have been formatted in £. why do you thin she is from UK?
meaix, could just be a honest mistake, besides, it's your own fault you wasted so much time, it only took me about 2 minutes to figure it was not solvable. I don't about anyone else.
To be honest, I had more fun proving to myself that this teaser was wrong than I usually have when a teaser is correct. That is of course no reason to accept an incorrect teaser, but I had more fun than meaix implies.
I agree with Bobbrt, did i spell that right? But I had more fun than i would have if it was right!
