There are five houses in a row and each house is a different color. A different man lives in each house and is 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 raise the same pet. Use the following 15 facts to determine who owns the fish. 1. The lives in a red house 2. The Swede keeps dogs 3. The Dane drinks tea 4. The green house is on the left of the white house 5. The green house owner drinks coffee 6. The person who plays polo rears birds 7. The owner of the yellow house plays hockey 8. The man living in the house right in the center drinks milk 9. The lives in the first house 10. The man who plays baseball lives next to the man who keeps cats 11. The man who keeps horses lives next to the one who plays hockey 12. The man who plays billiards drinks beer 13. The German plays soccer 14. The lives next to the blue house 15. The man who plays baseball has a neighbor who drinks water. Colors: Countries: Drink: Sport: Pet: Red Tea Polo Green Swede Coffee Bird White Dane Milk Baseball Cats Yellow Beer Billiards Blue German Water Soccer Fish Next, we need to create a table. We shall use the following categories: House Color Nationality Drink Sport Pets And so, now we shall use the above 15 facts to fill in the table. It is best not to go through the facts in order. Rather, by trying to use the options that limit the number of possibilities. We begin with fact #9 that the lives in the first house. Next we use fact #14 that the lives next to the blue house. Blue Now, we have to interpret fact #4 to mean that the green house is directly to the left of the white house. This gives us two possible options. Blue Green White Blue Green White Next, we use fact #1 that the lives in the Red house. (There is only one option in each of the two above.) Blue Green White Red Blue Red Green White Now, we can use both fact #5 (Green house drinks coffee) and fact #7 (Yellow house plays hockey). Note: The only remaining house has to be the yellow house. Yellow Blue Green White Red Coffee Coffee Next, we use fact #8 that the owner of the center house drinks milk. This eliminates our first possibility, so we see that the drinks milk. Milk Coffee Using fact #11 (the man with lives next to the man who plays ), we have the following. Milk Coffee Using fact #3 (The Dane drinks tea), we have two possibilities. Dane Dane Milk Coffee Tea Now we use fact #2 (The Swede has dogs) to create three possibilities. Dane Swede Dane Swede Swede Dane Milk Coffee Tea Now, it is easy to apply fact #13 (The German plays soccer). There is only one place that this fits in each of the above three possibilities. Dane Swede German Soccer Dane German Swede Soccer German Swede Dane Milk Coffee Tea Soccer Next, we use fact #12 (The man who plays Billiards also drinks Beer) to eliminate all but the second option, leaving us with just one option. Dane German Swede Beer Soccer Billiards Now, using fact #6 (The man who plays Polo also has birds), we see that it only fits with the. Dane German Swede Beer Polo Soccer Billiards Birds There is only one position for the man who plays Baseball (The Dane). Dane German Swede Beer Baseball Polo Soccer Billiards Birds Using fact #15 (The man who drinks Water is a neighbor of the man who plays Baseball) and fact #10 (The man with Cats lives next to the man who plays Baseball) to fill in the rest of the table. : We have to assume that in fact #15, neighbor refers to next door neighbor, not just one of the five nearby houses. Dane German Swede Water Beer Baseball Polo Soccer Billiards Cats Birds And so, we see that there is only one spot left not filled in. The question asks who owns the fish. Now, since we must assume that one of the five owns the fish, in which case the German would own the fish. Thus, our completed table looks like the following: Dane German Swede Water Beer Baseball Polo Soccer Billiards Cats Birds Fish
