Hi

Is there missing information here ? or can anyone explain why there are not lots of solutions:

The Puzzle: Four people are traveling to different places on different types of transport.

Their names are: Rachel, John, Mr.Jones and Cindy.

They either went on train, car, plane or ship.

* Mr.Jones hates flying

* Cindy has to rent her vehicle

* John gets seasick

There are at most 4! = 24 solutions and 24 is not a lot, is it?

Hi JaneFairfax,

If we're comparing the distance from my house to Billericay (=24 miles) with the distance to Alpha Centauri ( approx. 24807799074834.8 miles) then you are right.

But if the question was "How many Jimmy Grimbles are there?" then 24 is definitely lots!

Perhaps I'm being too narrow in outlook, but I expect logic questions to have just the one answer.

Well, this particular puzzle definitely does not have a unique solution. More clues are needed.

Hi JaneFairfax,

Thanks for confirming that.

I am always looking for sites with intelligent puzzles. Invariably, they all have stuff like. Notice that no question is even asked, but we should assume that we are meant to assign a vehicle to each person. We should also expect there to be only one solution. In order for this to be the case, we must read the clues from another point of view and get information that is the opposite of what we would expect. "John gets seasick." could be interpreted as, "John is prone to seasickness and therefore does not go by ship." or it could be interpreted as, "John gets seasick on this particular voyage, therefore he must be on the ship." Similarly, we can assume that Mr. Jones hates flying because he is required to do it all the time, including this trip. That means Rachel is on the train, Cindy is in a rented car, John is unhappily sailing on the ship, and Mr. Jones is not happy about being on the plane. This is the only answer I can find that is remotely satisfying, but it is still a very poor logic puzzle.

I think there is one and only one solution.

John gets seasick so he must be on the ship.

Cindy had to rent so she is using a car.

Mr. Jones hates flying so he booked the train.

Rachel is therefore on the plane.

hi nightstrider,

Wow. It's a while since I saw this thread. If you are interpreting 'John gets seasick' as meaning he is now suffering from this malady because he has unwisely chosen to go by ship, then I'm happy with your analysis.

That's the trouble with the English language; it can be ambiguous. It made me laugh when I heard this on the news: 'He sailed the Atlantic, single handed.

Most people interpret the puzzle differently; 'John gets seasick' = John knows he will suffer if he goes by ship so he avoids this option.

Nice try! Welcome to the forum.

Bob

ps. Sorry, I cannot comment there on your post about the professor because of a promise I made in post 56. I think I dealt with the fault in the student logic in post 50.

And I also demonstrated that you can make statements of this type logically and consistently and make them come true. That's what posts 56 and 65 were all about.

Answer to this is:

Cindy- Car

John- Ship as he gets seasick

Mr. Jones- Train as he hates flying

Rachel- Plane as it's the only one left
