[net.math] LOGIC PROBLEM

jeball@trwrb.UUCP (Jerome E. Ball) (05/25/85)

  This is for all the hardcore programmers, mathematicians or whomever else
  reads this net wonderland.

  LOGIC problem:

   BACKGROUND:    Five women attended college and became good friends.  After
                  graduation, they all moved away, but kept in contact with
                  each other.  They all had agreed to meet at the Tenth
                  Reunion of their graduating class.  Their names are ANN,
                  SUSAN, CINDY, PAT, and JACKIE.

   PROBLEM:       Figure out each woman's first and last name. Also, find out
                  what is each woman's home town.



           Ann and Ms. Davis were roommates; as were Cindy and Ms. Jones. Ms.
         Walters lived in a single apartment.

           Ms. Thomas was from Des Moines, Iowa; and Susan was from Miami,
       Florida.  Ms. Kerr was from Gary, Indiana; and Pat was from Cleveland,
       Ohio.  The other woman was from San Francisco, California.


  If anyone out there can figure it out send me elec. mail and let me watch
  all of you genius's get it wrong.  I will post the answers and how they
  are calculated later on some time.  Give it your best shot!!!!!!!!!

Find the OTHER woman!! and you'll find the soultion.
The other woman is Jackie Walters, from San Francisco. The rest of the
solution is trivial.

halle@hou2b.UUCP (J.HALLE) (05/29/85)

In a sense, the solution is trivial, since almost any combination works.
With the other woman being Jackie Walters from SF, there are two solutions.
But Jackie can have other last names that would yield valid solutions.
I have found six valid solutions; there may be more.

There is obviously some clue missing from the posting.  Either that or there
is some hidden meaning we are to discover.  (Jessica Walters once played
a San Francisco cop.  Is that why Jackie Walters from SF is a solution?
But Ann Davis was on the Brady Bunch, and Ann cannot be Ms. Davis.)

The simplest match-up seems to be by taking the names in order in each
case:

(names given)  (names in order      (names in order     (cities given)
                mentioned in         mentioned in
                roommate list)       city list)
-----------------------------------------------------------------------------

Ann            Ann                      Ms. Thomas  in  Des Moines, Iowa
                &
Susan          Ms. Davis                Susan       in  Miami, Florida

Cindy          Cindy                    Ms. Kerr    in  Gary, Indiana
                &
Pat            Ms. Jones                Pat         in  Cleveland, Ohio

Jackie         Ms. Walters              "other"     in  San Francisco
---------------------------------------------------------------------------

Again, this is done by just taking the names in the order they were given
in the three paragraphs.

Ann Thomas, Des Moines
Susan Davis, Miami
Cindy Kerr, Gary
Pat Jones, Cleveland
Jackie Walters, San Francisco

   The answer to the Logic Problem.  For those of you that have read my
 logic problem, i am now sending you the answers to get the results. 
 I recieved numerous answers to my problem, so far i have recieved 20
 replys with 5 people getting all the correct answers, some got 2 or 3
 but not all of them.

   Well it is quite simple the way it is derived.  All of the names and
 cities are listed in the same order each time.  Take the first first name
 and match it with the first last name and city, you do the same to the
 second first name and the second last name and city, etc..  The last woman
 whose name is fifth, you find by process of elimination.  That is all
 there is too it.  I hope i have not disappointed some of you.  Until next
 time.

So the fact that all the names and cities are in the same order is
supposed to define the solution?  HOGWASH!!!!!!!!  (I'd use something
stronger but this isn't net.flame.)  Nothing in the statement even
remotely suggests that information.  And listing it as a "logic problem"
absolutely excludes that restriction since it has nothing to do with
logic.  If you want to give a problem where the extra clues are hidden
(as I suggested might be the case), fine.  Those are worthwhile.  But
ones where you must invent a clue out of thin air are less than worthless.

Here's a similar one.  On Monday I give you a dollar, on Tuesday I give you
two dollars.  I proceed with this progression throughout the week.  After
I pay you on Sunday, how much will you have?  Whatever answer you give me
I will claim is wrong.  $28?  Nope.  I'll say it should be $127.  $127?
Nope, $28.  Either $28 or $127, depending on the third number?  Now you're
close, but you still don't have the right answer.  It's rotated below.
And if you don't like that answer, tough.  It's at least as fair as the
answer to the "logic problem."
