hats and snow
mu
blind.
A fourth person (D) enters with 5 hats - 3 black and 2 white - and places a
hat on A,B and C and then hides the remaining 2.
D then removes A's blind fold - so he can see what colour hat B and C are
wearing but not his own. D asks him if he knows what colour hat he is
wearing - he says he doesn't.
D then removes B's blind fold and asks the same question - B says he
doesn't know.
D then asks C if he knows what colour hat he's wearing - he says he does.
What colour hat is C wearing, and how did he know?
And any ideas on the following riddle?
Once was white as snow,
then green as clover,
then red as blood,
you know me well...

The riddle seems to describing a tree-covered landscape in winter,
spring/summer, and fall.

The blind man, C, must have a black hat.
Both A and B must have seen either two black hats or one black and one
white,
since two whites would let them know they had black. In both cases C
must
have a black hat.

I thought this is an apple: White flower, green when unripe, and red
when ripe.

1) A doesn't know his hat so the hat color of B&C is not Both white,
B & C = (Bl & Wh) or (Wh and Bl), or (Bl and Bl)

2) B Doesn't know, so C hat can be White (Because B will know that he
wear Black - see No. 1),

3) so C must be wearing BLACK.

Do A, B & C know that there are three black and two white hats? If
they don't, there's no solution.

A doesnt know the colour of his hat => he sees 2 black or a black and a
white hat
if B sees 2 white hats, he'll know his hat's colour
=> B sees 2 blacks or a black and a white one.
if C is wearing white, B will know that A saw a black and a white hat, so
his hat is black.
B doesnt know => C is wearing black ... and so he concluded
