The worlds first riddle!

The passage takes an hour less than 7 days (167 hours) and then the ship is in port 23 hours before returning.

The cruise line has ships which depart from NYC and London every day of the week at precisely 10:00 GMT.

So, a ship departs from NYC at 10:00 GMT, arrives in London at 9:00 GMT, then departs from London at 8:00 GMT? That means there are ships that depart at times other than 10:00 GMT.

Mark, we are just like trains that pass in the night

Mrs Stormy grumbles about bad time-keeping trains like everybody else. On one particular morning she was justified, though. The train left on time for the one hour journey and it arrived 5 minutes late. However, Mrs Stormy's watch showed it to be 3 minutes early, so she adjusted her watch by putting it forward 3 minutes. Her watch kept time during the day, and on the return journey in the evening the train started on time, according to her watch, and arrived on time, according to the station clock. If the train traveled 25 percent faster on the return journey than it did on the morning journey.

So I ask; was the station clock fast or slow, and by how much Question

One more thing on the digit problem. For part (b), a given ordering may provide multiple different solutions depending on the placement of the parens.

markr, just out of curiosity, how are you representing the digit problem with parens in the try-all-possibilities program? have you written a generic try-all program that you simply extend from case to case? i had written one too but i didnt take the time to think about how to incorporate parens.

"Bitch! and my name is yugi not yogi."

Yogi, deals entirely with the mind and psychic power and may be called the science of applied psychology. Its aim is to remove all mental obstructions and to gain a perfectly controlled, healthy mind. The main purpose of its training is to develop and strengthen the will as well as the power of concentration, and to lead the seeker after Truth through the path.

This path is called Raja Yogi or the Royal method (Raja means "king") because the power of concentration and will-power are not only greater than any physical force, but are essential to the acquisition of all other powers. A person who possesses a vigorous mind controlled by a well-developed will, with strong power of concentration, can easily become the master of physical nature and in a short time attain the realization of Truth; and it is the special province of Raja Yogi to teach how this can be accomplished. Its study has been encouraged by all those who have come in contact with the Raja Yogis of India either in ancient or modern times. It was extolled by Pythagoras, by Plato and the Neo-Platonists like Plotinus, Proclus, and by the Gnostics.

Should I wish to discuss the price of Yugi Gummy Bears with you, I will let you know.

In the meantime, Yogis rules - ok!

Stu ordered a length of rope by telephone from his hardware store. But when he went to collect the rope, he found that the assistant had miswritten the order by interchanging feet and inches. As a result of this, the rope was only 30 % of the length that he wanted.

So, what length did he want and what length did he get Question

Rather than figure out all the ways parens can be used, I'm generating all possible postfix notation strings and evaluating them. I got the idea from somebody at another site for a similar problem. I got 58,130 postfix strings that evaluate to 30.

My next task (after my son gets off the computer with my development tools) is to weed out duplicates per your definition (identical ordering of operators). Some "duplicates" will likely be different (precedence modified by paren placement) solutions. After that, I intend to determine the number of solutions that don't require parens.

OK guys, I've done a bit of research to find out just what we're dealing with here.

Yugi is not a 14-year old girl from Indiana. He's a character in a game. This is from some site that has a parent's guide to Yu-Gi-Oh.

Check out this comment from the site:
The Japanese versions of Yu-Gi-Oh (at least the early ones) were a bit racy and included some concepts that might not be appropriate for some children. U.S. versions have been sanitized by the licensees to remove any inappropriate content. We do not think many parents would have trouble with the current content, but encourage you to make your own informed decision.

Clearly, we're dealing with an early Japanese version (see language from Yugi in previous posts).

For those who are interested in a bit of Yugi's background, here's the story line:
Yugi's grandfather runs a game store. One day Yugi learns of a very, very old Egyptian card fighting game called "Duel Monsters", In the game, different creatures battle in magical duels. Besides just battling themselves, they also have to contend with a changing battlefield that holds many dangers. When the battle is over, only one beast rises to be called Yu-Gi-Oh! (King of Games).
Along the way Yugi solves the secret of an ancient puzzle (Millennium Puzzle) and releases the spirit of an Egyptian King, Yami Yugi. With help from the King's spirit, Yugi sets out to become King of the Duelists. In the past Yugi led a mild mannered, quiet life. Now his friend, Joey, helps him deal with his much greater responsibilities. With Joey's help and the strong energy he receives from Yami Yugi, he is ready to face the challenges ahead.

One of his opponents, Seto Kaiba is very rich. Kaiba becomes very upset when Yugi beats him. He now wants to beat Yugi however possible. Kaiba and his younger brother Mokuba were raised in an orphanage. Kaiba promised to support and take care of Mokuba and appears to be easily able to do so as head of his own international hi-tech company, Kaiba Corp. But Kaiba focuses all his energy and business skills on Duel Monsters. He challenges Yugi.

markr thinks I wanted 9'2".

Actually, he's wrong. I'll never tell how many feet I wanted, and there is not information to figure it out from the riddle because you only supplied 1 equation:

0.3(12A+B) = 12B+A

which simplifies down to A = 4.5B

There are infinite solutions even if you restrict your solutions to integers.

But not if 0 <= inches < 12.

Alright, but that should have been stated. I mean, we are talking about someone who works in a hardware store yet doesn't know the difference between feet and inches.

If I can read 8/8 cups of sugar in a recipe book and interpret that as 1 cup, I don't think we can rule out the possibility that the hardware jockey might take 6'27" literally.

DIGIT PROBLEM
I generated all possible postfix strings for this problem. For the ones that equaled 30, I determined the infix order of operations and eliminated duplicates. I found 16828 unique operator orderings that solve the problem. So, just over one fourth of the possible (65536) operator orderings yield a solution. I still don't know how many don't require parens.
