HELPP logic problem
Who Owns The Fish?
There are five houses in a row and in five different colours.
In each house lives a person from a different country.
Each person drinks a certain drink, plays a certain sport, and keeps a certain pet.
No two people drink the same drink, play the same sport, or keep the same pet.
* The Brit lives in a red house
* The Swede keeps dogs
* The Dane drinks tea
* The green house is on the left of the white house
* The green house owner drinks coffee
* The person who plays polo rears birds
* The owner of the yellow house plays hockey
* The man living in the house right in the centre drinks milk
* The Norwegian lives in the first house
* The man who plays baseball lives next to the man who keeps cats
* The man who keeps horses lives next to the one who plays hockey
* The man who plays billiards drinks beer
* The German plays soccer
* The Norwegian lives next to the blue house
* The man who plays baseball has a neighbour who drinks water.

The fish is of the danish people

Re: HELPP logic problem
Hi G_Einstein;
Funny you should work on this because this is a problem first posed by Albert Einstein but some clues have been left out or changed. Tennis is changed to polo, chess is changed to hockey, poker is changed to baseball and golf to soccer. This doesn't affect the solution which he gave as the German owns the fish but I have also seen on one occasion the Dane owns it.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: HELPP logic problem
To solve this problem you need to do a "logic grid" (for you visual/logical types)
This grid will be a 6X6 straight-edged triangle
Each of the parts of the triangle will be subdivided into 5x5 squares
So you'll get something that looks like :
___________________________________________________
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
|_|_|_|_|_|
Every Row and every column will be singular to one type of item (in this case Color, house order, Nationality, sport, beverage, pets).
Make sure you put them in order
Color, house order, Nationality, sport, beverage, pets
Color
House Order
nationality
Sport
Beverage
Pets
Now, what you have to do is put an "O" where the information checks out (let's say the Brit has a red house, you will put a O at the red/Brit intersection)
and an "X" where it doesn't (If the Brit has the red house, that means that "Brit, any other color" combination or the "red, any other nationality" will have an X in them).
You will quickly realize that the 5x5 squares that cross the same categories (Color, color), (house order, house order), etc. will have one long diagonal of "O"s that will go through the whole grid. The rest of these 5x5 squares will be filled with Xs (these 6 squares are required at the end of the process to do "filling")
Anyway... Insert logic here and continue filling the grid (considering the fact that multiple 5x5 squares depend on each other). Make sure to revise the logical order of some clues (the Norwegian lives next to the blue house, etc.).
Here's a summary of the different logical operators :
Brit IS Red
Swede IS Dog
Dane IS Tea
Green ISN'T White
Green IS Coffee
Polo IS Birds
Yellow IS Hockey
#3 IS Milk
Norwegian IS #1
Baseball ISN'T Cats
Horse ISN'T Hockey
Billiard IS Beer
German IS Soccer
Norwegian ISN'T Blue
Baseball ISN'T Water
Fish IS ?
House Rank
# Green IS # White - 1
# Baseball IS # Cats +/- 1
# Horse IS # Hockey +/- 1
# Norwegian IS # Blue +/- 1
# Baseball IS # Water +/- 1
NOW THE ANSWER! (for your version)
Using these logical operators and the hints, we find that :
The first house is yellow and in it lives the Norwegian that plays hockey, drinks water and keeps cats
The second house is blue and in it lives the Dane that plays baseball, drinks tea and keeps horses
The third house is red and in it lives the Brit that plays polo, drinks milk and keeps birds
The fourth house is green and in it lives the German that plays soccer, drinks coffee and keeps FISH!
The fifth house is white and in it lives the Swede that plays billiard, drinks beer and keeps dogs.
If you need more clarifications as to how to use the logical grid, either e-mail me at aishot_zesharif@hotmail.com
You can either make the grid on paper or in Excel (I used Excel).
Or post here... I'll check back for a month or two to help out!
Hope this wasn't redundant and that no one already explained this

Re: HELPP logic problem
Hi;
I think I mentioned above it has been solved here.

Does your work prove this is wrong?
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
