Prob.  Party Favors (S594)
From: Puzzles And Brain Teasers on 6/5/2008
Source: (Removed from apuzzlezone.com/adailypuzzle)
Sheila, buying favors for a party
she was giving, was
having difficulty deciding on
how many more favors to buy.
She started out by planning
to give everyone three favors,
but when she divided the favors
she had by 3, she had one
left over; when she divided
by 4, she had two left over;
by 5, she had three left over;
and by 6, she had four left
over. Since she was going
to have ten guests, this would
not work. She counted
the favors and realized that, by
adding two more, she could divide
the favors evenly. What
is the smallest number of favors
she could already have
bought to meet those specifications?

PROB.  Hairs On The Head (S602)

Source: (Removed from apuzzlezone.com/adailypuzzle)
Given that there are more people
living in Dublin than there are
hairs on the head of any Dubliner,
and that no Dubliner is totally
bald, does it necessarily follow
that there must be at least two
Dubliners with exactly the same
number of hairs?
Here is a variant of the same
problem: on the island of Alopecia,
the following facts are true:
1. No two islanders
have exactly the same number of hairs.
2. No islander
has precisely 450 hairs.
3. There are more
islanders than there are hairs
on
the head of any one islander.
What is the largest possible
