First draw a grid like follows
Code:
House |_|_|_|_|_|
Man |_|_|_|_|_|
Drink |_|_|_|_|_|
Smoke |_|_|_|_|_|
Pet |_|_|_|_|_|First the most obvious ones that gives us definite values
1. The Norwegian lives in the first house.
2. The man living in the center house drinks milk.
So we have
Code:
House |___________|_|______|_|_|
Man |_Norwegian_|_|______|_|_|
Drink |___________|_|_Milk_|_|_|
Smoke |___________|_|______|_|_|
Pet |___________|_|______|_|_|So we continue with the clues
3. The Norwegian lives next to the blue house. (As the Norwegian lives on one end he only has one neighbour)
4. The green house is just to the left of the white house. AND The green house's owner drinks coffee. (Using these together the only place that the 2 houses will fit is #4 (green/coffee) and #5 (white)
5. The Brit lives in the red house. (Only one house left with both colour and man missing. So the Brit goes to the center house. From this we see the remaining colourless house (#1) must be yellow)
6. The owner of the yellow house smokes Dunhill. (From 5 we get this to be the first house)
7. The man who keeps a horse lives next to the man who smokes Dunhill. (Dunhill smoker has only one neighbour)
8. The Dane drinks tea. AND The owner who smokes Bluemasters also drinks beer.
These two clues will provide us with the water drinker.
The Dane drinks tea: can either be in house 2 or 5 as they are the only houses without an owner and drink
The owner who smokes Bluemasters also drinks beer: also can only be in house 2 or 5.
So we get that between house 2 and 5 the drink must be beer or tea. This leaves water to be the drink in house 1.
9. The man who smokes Blends has a neighbor who drinks water. (Easy solution after
10. The owner who smokes Bluemasters also drinks beer. (Only house left without both drink and smoke is house #5)
11. The Dane drinks tea. (Only house left without owner and drink is #2)
12. The German smokes Prince. (Only house left without owner and smoke is #4)
13. The person who smokes Pall Malls raises birds. (Only house left without smoke and pet is #3)
14. The Swede keeps dogs as pets. (Only house without owner and pets is #5)
15. The man who smokes Blends lives next to the one who keeps cats. (We know his one neighbour (#3) keeps birds, so the other (#1) must be the cat owner.
This leaves us with only one open square in the grid. The pet of house #4.
