are you smart enough to solve the puzzle?

so, you've been offered to solve this quiz created by Einstein before. and well, let me share with you on how to solve the matter step by step. thank me later for understanding this, if you didnt.

There are 5 houses in 5 different colors. In each house lives a person with a different nationality. These 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar or drink the same drink.

Here’s the question: Who owns the fish?

1. The Brit lives in a red house
2. The Swede keeps dogs as pets
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 smokes Pall Mall rears birds
7. The owner of the yellow house smokes Dunhill
8. The man living in the house right in the middle drinks milk
9. The Norwegian lives in the first house
10. The man who smokes Blend lives next door to the one who keeps cats.
11. The man who keeps horses lives next door to the man who smokes Dunhill
12. The owner who smokes Blue Master drinks beer
13. The German smokes Prince
14. The Norwegian lives next to the blue house
15. The man who smokes Blend has a neighbor who drinks water

you should start putting things in table. it will make things easier for you. let's start with those straightforward clues.
8. The man living in the house right in the middle drinks milk
9. The Norwegian lives in the first house
14. The Norwegian lives next to the blue house



we know what green house is on the left of the white house (point no.4), so we need to figure out whether white house is located at the far right, or second from the right. for that, we need to scan through for more clues. and you'll come to: 5. The green house owner drinks coffee
this means green house cant be at the middle, and since it has to be located left of the white house, it becomes:



point no.1 tells us that Brit lives in the red house, so we're only left with 'yellow house' for the 1st house, and red will be house no.3
and we should just need to fill in the rest clues into the table.
7. The owner of the yellow house smokes Dunhill
11. The man who keeps horses lives next door to the man who smokes Dunhill



We're left with this clues:
2. The Swede keeps dogs as pet = either House 4 or House 5
3. The Dane drinks tea = House 2 or House 5
6. The person who smokes Pall Mall rears birds = House 3; House 4 or House 5
12. The owner who smokes Blue Master drinks beer = House 2 or House 5
13. The German smokes Prince = House 2; House 4 or House 5

So, here's the solution in sequence:
1) We're wondering what does Norwegian drinks (either tea, water and beer left). Tea is out as it's for House 2 and 5; cant be beer as the beer drinker smokes Blue Master), thus, it's 'Water'.
2) The man who smokes Blend has a neighbor who drinks water
3) The man who smokes Blend lives next door to the one who keeps cats.
4) The owner who smokes Blue Master drinks beer. Well we were wondering if beer is for House 2 or House 5, but since House 2 smokes Blends, we're only left with House 5.
5) Tea is the only left-out, so it's for House 2 and that means we find out where Dane stands.
6) The German smokes Prince -> only House 4 left for this clue.
7) The Swede keeps dogs as pets -> only House 5 is available for Nationality

Last clue, but not least: 6. The person who smokes Pall Mall rears birds -> we're left with House 3 for Pall Mall smoke, and there goes Pall Mall and Birds.

So, who keeps the fish? I guess you know now.
