• 1.) For Medical Purposes.
  
  Captain Kirk of the Star Ship Enterprise, brought aboard 28 bottles
  of brandy - for mediacl purposes - which he kept in the ship's
  "wine cellar", a three-by-three-foot storage bin in his quarters.
  Suspecting that some crew members might try to take off with a
  bottle or two for recreational purposes, he arraged them in the
  bin as shown bellow, so that nine bottles can be counted on each
  side. In this way, he felt, he could tell at a glance if any were
  missing.
  
  
  
  During the next party on C deck, howerver, the first mate snuck
  into the storage area and appropriated four of the bottles, then
  rearanged the ones that remained so that when the captian next
  checked his cache, he would still count nine bottles on each side
  of the bin.
  
  A few days late, the navigator decided to pep up a party using the
  same technique. He also stole into the secret room and took four
  bottles, then rearanged the rest so that when the captain next
  checked, there would still be nine bottles visible on each side
  of the bin.
  
  How, during their covert operations, did the first mate and the
  navigator each arrange the bottles?
  
  
• 2.) The diagram above serves double duty:
  Use it again for this puzzle, ignoring the numbers. Now it represents a new building with eight appartments four at the sides and four at the corners.
  The housing director has received a complaint from some tenants in
  the building: Aparently twice as many people have a southward view
  (toward a garbage dump) as look east (toward a sheet-metal factory).
  Those who have a view to the west (toward another apartment building)
  are only one-third as many as look south, while the lucky tenants
  with a northerly view (toward the park) are only half as many as look
  east, toward the sheet-metal factory.
  There are 20 tenants in the building, all told, and there is at least
  one in each apartment. How many people occupy each apartment?

• 6.) Three Squares.
  Can you trace the design below-three overlping squares
  in one continuous line, without lifting the pen from the
  paper and without retracing any line?
  
  
  
• 7.) Target
  This design below shows three concetric circles with a line trough the center. It is possible to draw the
  figure in one continuous line, without any line crossing another,
  and without lifting the pen from the paper. how would you do it?
  
  
  
• 8.) Circle Sqaured.
  This geometrical design ("see CirQube.iff or CirQube.gif")
  has four squares at alternating angles inside a circumscribed
  circle-can also be drawn in one continuous line, without lifting
  the pen from paper, and without going over any line twice.
  Can you do it?
  
  
  
• 9.) Clock Problem.
  A clock loses four minutes every hour. It was set correctly
