G'Day teamsters, in an attempt to alleviate some enmity within the posters in this board, i deliver to you all some puzzles!!
AVAGOYAMUGS !!

** There are two rooms, in one there are three lights, in the other there are three switches; you cannot see one room from the other, each switch controls only one of the 3 lights. What is the fewest number of trips you have to make to the other room to know which switch goes to which light? **

**A man was changing a flat tire when all 4 nuts used to hold the wheel in place rolled into the sewer drain where they were irretrieveable, yet he was still able to drive off in the same car. How?**

** In Hawaii, if you drop a steel ball weighing 5 pounds from a height of 5 feet, will it fall faster in water 20 degrees Fahrenheit, 40 degrees Fahrenheit, or will there be no difference at all?**

This ones a mongrel !

**You have an unknown quantity of pennies laying on a table. You're blindfolded and wearing gloves (so you can't feel the pennies face.) 10 of the pennies are heads up, the remaining all have tails facing up. Your challenge is to divide the pennies into two groups so that there is an equal number of heads facing up in each group. You can pick them up, shake them up, do whatever you want just as long as you don't look at them or feel the face to determine which way the penny is. The two piles don't need to have an equal number of pennies, just an equal number of heads facing up. How do you do it? Good Luck!

Cheers

sorry i forgot this beauty.......

**A boy buys a 5 foot long fishing pole in town. After buying it he goes to the bus stop to catch a ride home. When the bus arrives he begins to get on the bus. The bus driver stops him and says "You can't bring that thing on the bus." The boy asks "Why not?" The bus driver tells him "There is an ordinance that says you can't bring anything on the bus longer the 4 feet. The fishing pole you have looks to be 5 feet. Sorry kid." With that the bus driver boots the kid off the bus. He goes back to the store where he bought the fishing rod thinking he'll just return it and buy it the next time he's in town. When he returns to the store he finds they have a "No Returns" policy. The boy then gets an idea and 10 minutes later he is on the bus heading home WITH the fishing pole. He didn't break it, bend it or take it apart. It was still in it's original condition. How did he get it on the bus and remain legal under the ordinance?**

First puzzle;

Second Puzzle:

Take one nut off the remaining three wheels and use them on the one that had none.

Third Puzzle:

Hawaii? the water at 20 degrees F would be frozen so it probably wouldn't fall as fast as in the 40 degree water.

Fourth Puzzle:

I'm not sure about that one: How about this? you put all the pennies standing on thier side so that there are no pennies facing heads up.

Vampireman,

You did not say what kind of lights there were, but if they are incandescent lights, I say you only need one trip. Turn on one light bulb and wait about 15 minutes. Then turn on a second bulb. Go to the room. You already know which one you didn't turn on since that bulb will be dark. The one you turned on first will be hot, and the one you just turned on will not be hot.

This one is where a little trig comes in handy. The boy buys a box that is 4 feet long and wants to put the fishing reel in it diagonally. But how wide should the box be?

If the fishing pole is the hypoteneuse of a right triangle and the 4' box is one side then we have:

4^2 + x^2 = 5^2

or 16 + x^2 =25

or x^= 25-16 (9)

Therefore the box is 4' long by 3' wide and the pole will fit in it diagonally.

I'm still thinking about the pennies one.

Puzzles 1 to 3 are basically answered.

here is number 4:

Choose ANY 10 pennies to form one group and the rest will be the other group. Now take this group of 10 pennies and turn EACH penny upside down.

The other puzzle:

The boy bought a box that was 4 feet long and 3 feet wide. The diagonal of the box then would be 5 feet long. Just perfect for his fishing pole.

gd,

: Choose ANY 10 pennies to form one group and the rest will be the other group. Now take this group of 10 pennies and turn EACH penny upside down.

Since you don't know which 10 pennies are facing up, and you have to randomly take any 10 pennies to form your group, if only one penny in that group of 10 has a head facing up before you turn it, then your solution fails.

Am I missing something here?

Here's a fun one.

You see a ship at dock at 5:00 in the morning. The side of the ship has 1 foot marks that show the water line. The water line shows 30 feet. The tide rises one foot per hour up to maximum of 12 feet by 5:00 p.m. in the afternoon. You come back at 4:00 p.m. What will the marking on the ship's water line show?

Am I missing something here?

Yes. Take any ten pennies, x coins will have heads up, y coins will have tails up, x+y=10, which means that in the other group y coins will have heads up. When you flip the 10 you took aside, x coins will be tails up, and y coins will be heads up. This works no matter which coins you pick.

Fark,

If we take 10 pennies from the original group and only 1 of them had heads facing up....that means there are 9 with heads facing up in the original group right?

OK so in my selected group of 10 we turn them all over.....that means the 9 tails now become 9 heads and the other one flips to tails...thus giving you 9 with heads up in each group.
