There are 3 black hats and 2 white hats in a box. Three men (we
will call them A, B, & C) each reach into the box and place one
of the hats on his own head. They cannot see what color hat they
have chosen. The men are situated in a way that A can see the hats
on B & C's heads, B can only see the hat on C's head and C cannot
see any hats.
When A is asked if he knows the color of the hat he is wearing,
he says no.
When B is asked if he knows the color of the hat he is wearing he
says no.
When C is asked if he knows the color of the hat he is wearing he
says yes and he is correct.
What color hat and how can this be?

The owner of the local bank found a $50 bill lying in the gutter;
he picked it up and made a note of its serial number. Later that
day his wife mentioned that they owed the butcher $50, so the banker
used the bill he'd found to settle up with the butcher. The butcher
used it to pay a farmer; the farmer in turned used it to pay his
feedstock supplier; and the feedstock supplier used it to pay his
laundry bill. The laundryman used it to pay off his $50 overdraft
at the local bank. The banker recognized the bill as being the one
he had found in the gutter, but als noticed, on closer examination,
that it was a fake. By now, it had been used to settle $250 worth
of debts. What was lost?
