We are given a series of constraints. Let us label the houses from 1 to 4 (left to right), with House 1 being the leftmost.
Clue: The Norwegian lives in the first house on the left → House 1 = Norwegian
Clue: The Norwegian lives adjacent to the blue house → House 2 = Blue
Clue: Tea is drunk in the blue house → House 2 = Blue = Tea
Clue: The Italian drinks tea → House 2 = Italian
Clue: The Englishman lives in the red house → So Englishman must live in red house
Clue: The white house is to the right of the red house → White house comes after red
Clue: In the second house from the right they drink milk → House 3 = Milk
Clue: The Spaniard drinks fruit juice → yet to be placed
Now placing:
House 1: Norwegian (can’t be blue — adjacent to blue), so it must be Yellow
House 2: Blue (adjacent), Italian, Tea
House 3: Milk (by position), could be Red (for Englishman) — let’s test
House 4: White (must be to right of red) → So House 3 = Red, House 4 = White
Final setup:
House 1: Yellow, Norwegian
House 2: Blue, Italian, Tea
House 3: Red, Englishman, Milk
House 4: White, Spaniard, Fruit Juice
Hence, the Norwegian lives in the yellow house.
