When First the Marriage Knot was Ty'd
by Erik Oosterwal

This little puzzle comes from a book honoring the great puzzle
master Martin Gardner.  In the chapter titled Some Diophantine
Recreations, David Singmaster presents the following poem which
appeared in The American Tutor's Assistant, in 1791.

When first the marriage knot was ty'd
Between my wife and me,
My age was to that of my bride
As three times three to three
But now when ten and half ten years,
We man and wife have been,
Her age to mine exactly bears,
As eight is to sixteen;
Now tell, I pray, from what I've said,

What were our ages when we wed?

the organization's sign of "a good thing" to her clothing.
As a result, she met many objects of charity as she proceeded

what she had left.  To the third beggar she gave three cents
more than half of the remainder.  She now had one penny left.

There is a well-known story (the details vary) of a father
who, when he died left his seven camels to his three sons
in the following way: The eldest son was to receive one
half of the camels, the middle son was to receive one fourth,
and the youngest was to receive one eighth.  This will
disturbed the sons greatly, because it seemed to necessitate
cutting some of the camels into pieces.  The family's wise
neighbor volunteered to solve the problem for them.  He added
one of his own camels to the herd, bringing the number up to
eight.  Then the eldest son received four, the middle son
received two, and the youngest son received one camel.  The
wise neighbor then took back his camel, and everyone was
happy. Kinda amazing, huh? Was this solution fair?

Three mathematicians are applying for a job.  There are 5
hats, 3 white, 2 black. They're lined up, and a hat is
placed on each.  The first person in line cannot see any
hat; the second in line sees only the hat of the person
in front of him; the third person sees only the hats of
the two people in front of her.  The first person to
correctly figure out what color hat they have gets the
job; you guess wrong and you are killed. Assume these
are INTELLIGENT  mathematicians, and that they will do
the logically correct thing  at each stage -- if something
can be deduced, they will.  After a  long pause, the first
person, who cannot see any hats, says he knows  the color
of his hat. What is the color, and how does he know?

Consider a 5 by 5 Chess Board. Is it possible to place
5 Queens on the board such that three pawns can safely
be placed on the board? (aka, by carefully choosing where
to place the 5 queens, can you arrange it so that there
are 3 squares on the board that none of the queens can
attack)
