## Solution

• Let us start by arranging the data methodically, and then we will add it to a table.

We know that there are 5 people with 5 different parameters:- house color, nationality, drink, smoke, and pet.

From the hints, we know that:-

• House 1 belongs to the Norwegian (clue no. 9)
• The second house is blue(clue no. 9 and clue no. 14)
• The greenhouse is on the left of the white one(clue no. 4), but the greenhouse can’t be the center one ( clue no. 5 and clue no. 8) . Therefore it is the fourth house and the white is the fifth house(clue no. 4), leaving the center to be red and the first to be yellow.
• The red house belongs to the Brit(clue no. 1)
• The one living in the green house drinks coffee. (clue no. 5)
• The one in the yellow house smokes Dunhill and the one next to him has a horse. (clue no. 7 and clue no. 11)

• After this point, the puzzle gets trickier.

Now we start the process of elimination, by referring the above table.

• Among the remaining parameters, we know that the one who drinks beer also smokes BlueMaster.(clue no. 12)
• Therefore it can’t be the Norwegian or Brit. The Brit drinks milk and the Norwegian smokes Dunhill. (from the table)
• We also know that Dane drinks tea so he is living in houses 2 or 5. (clue no. 3) Also since the Dane drinks tea the only option left for the Norwegian is water.
• The Swede has dogs, therefore he is in house 4 or 5. (clue no. 2)
• Since Norwegian drinks water, his neighbor is the one who smokes Blend. (clue no. 15)
• Then the one who smokes BlueMaster and drinks beer is in house 5. (clue no. 12)
• Since Dane is drinking tea, not beer we can assume he is in house 2, (clue no.3) and the German is in house 4 since he smokes Prince(clue no. 13) leaving the Swede in house 5 and has a dog.
• From here we can say the Brit smokes Mall and has birds. (clue no.6)
• Finally, the Dane smokes Blend and his neighbor has a cat, which is Norwegian since his other neighbor has birds(clues no.10 and 15)
• Leaving the German, who has fish. (the process of elimination)
