17. 2

18. 32 (216 was all possible combinations)

19. 2

20. 2*sqrt(5)

Taking a different view... I- 8 + 8 + 8 = I + 8 + HI

Up side down you see this:
IH + 8 + I = 8 + 8 + 8 - I

Changing I's into 1's

1H + 8 + 1 = 8 + 8 + 8 - 1
1H + 9 ..... = ...... 23
14 + 9 ..... = ...... 23

So remove a part of the H to make a 4.


Whim

16 + 8 = 4.

16 + 8 = 4! add

13- 10 = 13

13 - 0 = 13 remove

XXX - IL = L + L / - L
LXIV = IIIII / X

CORRIDORS
Are the corridors closed at the far ends? Is this about catching him before he escapes an open system, or about avoiding an endless search in a closed system? Do we know how much of a head start the criminal got?

Mark asks, "Have you got a spare $5 Bucks buddy?"
No, wait. That might not have been him; it had more of a southern twang about it.

However Mark did say:

"Are the corridors closed at the far ends?"

A. They sure are.

"Is this about catching him before he escapes an open system"

A. Nope.

"about avoiding an endless search in a closed system?"

A. Yep.

"Do we know how much of a head start the criminal got?"

A. We sure do, about as long as it would take me to get from here to there. However, not more than two days. Give up now, save your sanity.

HINT. If the corridors are to long, there could be a problem.

Whim,
7168 = 75
7+68 = 75

Easy peasy.

If it takes two men three hours to dig a hole, how long does it take four men to dig half a hole


A cowboy rode into town on Friday, and rode out again two days later, on Sunday. How could he do this

A woman had two sons who were born in the same hour of the same day in the same year, but they were not twins. How could this be

AORALS
X-V=V-V
X-V=V=V

DIGGING
No such thing as half a hole.

COWBOY
Well, Sunday is two days after Friday; so he didn't have to resort to riding horses named Friday and Sunday.

SONS
There was a third child. They were triplets.

CORRIDORS
I think the cop can catch the thief if the corridors are no longer than 6 meters.
Here's the algorithm. It assumes the thief's luck lasts as long as possible.
Run to the end of corridor A, and come back to the room.
The thief must now be in corridor B or C.
Go 1 meter into corridor B, and come back to the room and light corridors A and C.
Go 2 meters into corridor C, and come back to the room and light corridors A and B.
Go 3 meters into corridor B, and come back to the room and light corridors A and C.
Continue this until the thief is caught.

If the corridors are 6 meters long, the thief remains free the longest if he is at the end of corridor C. When the cop goes from C4 to B5 to the room (14 meters), the thief goes from C6 to A1 (7 meters) and is caught when the cop lights corridor A.

However, if the corridors are 7 meters long, the thief can sneak into corridor A. When the cop goes from B5 to C6 to the room (17 meters), the thief goes from B7 to A1.5 (1.5 meters into A).

Aorals:

0 = 1

01 = 1

Mark, I think your answer is very well thought out.

I saw it this way. The cop can walk one of the corridors to the end and ensure that the bum is not there. Now he has two corridors - A and B - and he knows that the bum is farther than a0=1 in A and farther than b0=1 in B. The cop runs x0=b0+1=2 meters into A and back in x0 seconds. Now a1 = (x0+1) - x0/2 = x0/2 + 1 = 2 (the cop inspected x0+1 meters of the corridor A, but in x0/2 seconds that he ran back, the bum could reclaim x0/2 meters).

In the corridor B, the bum could make it to the room in b seconds and run into the "clean" corridor for another 1 meter, but the cop is already in the room and he will see the bum, so he can be sure that the bum is still in B, so b1=1. Next, the cop runs x1=a1+1=3 meters into B and back in x1 seconds. Now b2 = x1/2 + 1 = 5/2 and a2 = 1. Thus xn+1 = an+1 + 1 = (xn/2 + 1) + 1 = xn/2 + 2 which converges to 4, thus the maximum corridor length is 5(ish)

Who said they were easy?

The day before yesterday Cindy was 17. Next year she will be 20. How can this be

A cabdriver picked up a woman who was a notorious chatterbox. He didn't want to engage in conversation so he pretended to be deaf. He pointed to his ears and his mouth to indicate that he could neither hear nor speak.
As she was about to get out of the taxi, he pointed to the meter so she would read how much she owed. She paid him and walked off. Then she realized he could not have been a deaf-mute.

How did she know



Professor Mumbles held up a vial of bubbling liquid and said "Class, I have a substance in this bottle that will dissolve any solid it touches. I intend to ..." A student from the back of the room interrupted the Professor and said, "You have the wrong bottle!"

However to put an end to his winning streak, I propose the following:


Mother was making her favorite recipe for peach jam. Just as she was about to put the pot of jam on the stove, she noticed that the recipe called for one lemon for every dozen peaches. The recipe would be ruined if she didn't add lemons, but the peaches were already pureed into a jam mixture.

How can Mother find out how many lemons to put into the jam

Becky and Michael were playing in the house and accidentally smashed the picture window. "Oh, Mother will be so angry when she finds out," said Becky. "I know what to do," said Michael. He went outside and found a large rock and put it in the middle of the room.

When Mother came home from shopping the children told her that someone threw a rock from outside and smashed the window. Mother was very angry, not because the window was broken, but because the children lied.

How did Mother know the children were not telling the truth

I like to create new puzzles, puzzles that you have not seen before. But I think that anybody who can solve puzzles, can also come-up with new ones. So you can too. Often when one is trying to solve a puzzle one mind is getting strange ideas as how to solve it. It's those hairbrained ideas that can be turned into a new puzzle.

Once a new puzzle is presented, we should persue to create more of them.
