Math Prob. - Find A Four-Digit Integer II (S652)
From: The Puzzlet Page on 7/9/2009 Drawing from Valdosta State University |
Find a 4-digit integer has the
following properties:
The sum of its
first and third digits equals
the sum of the other digits.
The product of
its first and last digits is ten times
greater than the product of the remaining digits.
The sum of the
first two digits is only half
the sum of the last two digits.
What is the integer? Is
there more than one answer?

Math Prob. - Cheap Sheep...Bleat! (S651)
From: MathNexus.wwu.edu on 2/15/2009 Drawing
from MathNexus...
|
 |
A brother and a sister inherited
a herd of sheep. They
sold all of them, receiving
for each sheep the same
number of dollars as there were
sheep in the herd.
The money was given to them in
$10 bills except for
an excess, less than $10, that
was in silver dollars.
They divided the bills between
them by placing them
on a table and alternately taking
a bill until there
was none left.
"It isn't fair," complained the
sister. "You drew
first and you also took the
last bill, so you got
$10 more than I did."
To even things up partially,
the brother gave his
sister all of the silver dollars,
but she was still
not satisfied. "You gave me
less than $10," she argued.
"You still owe me some money."
"True," said the brother. "Suppose
I write you a check
that will make the total amounts
we each end up with
exactly the same."
This he did. What was the value of the check?

Math Prob. - Safe Safe (S650)
From: MathNexus.wwu.edu on 3/15/2009 Drawing from MathNexus |
To open a safe, Stu Dent knows
that the combination is three
single digits (0 - 9).
For example, the digits 5-4-9 formed
his old combination... that
is until his clever sister Pepso
Dent rekeyed the safe to a new
combination.
But Pepso did leave the cryptic
message: "To brother Stu who
acts so wise!... The new combination
is the last three digits
of 
Stu Dent asks for your help...What is the new combination?

Jack and Jill went up the hill,
To fetch a pail of water;
Jack fell down, and broke his
crown,
And Jill came tumbling
after.
Then up Jack got and off did

As fast as he could caper,
To old Dame Dob, who patched
his nob
With vinegar and brown

Math Prob. - Eight Gallons Of Wine (S646)
From: MathNexus.wwu.edu on 5/30/2009 Drawing from MathNexsus.wwu.edu |
Two men purchased an 8-gallon
cask of wine, and desired
to divide it equally; but they
had only two measures
wherewith to do so, a 5-gallon
measure and a 3-gallon
measure. How can they
perform the division?
.
| To see the solution click | . |
 |
If the depth is the same, a square
pan holds the same amount
as a round one measuring 1 inch
more across. For example,
an 8" square pan holds the same
amount as a 9" round one.
Question 1: Why is the first
statement quite incorrect....
Hint: Should it matter what
the depth of the pan is?
Question 2: For the second claim,
what is the value of pi
being used to make this equality
"work"?
Question 3: For what sizes of
pans is this estimate good?
Turns out for a square 8" pan,
the estimate of a 9" circle
is very close.
