If you participated in the True Detective event of FGS Science Carnival 2015 at FFC Grammar School, Mirpur Mathelo, you would have encountered a modified/localised version of the Einstein Puzzle. If you haven’t attempted it before, I will highly recommend you to try it first and then see the solution below.

###The Puzzle: There are 5 houses in 5 different colours. In each house lives a person of a different nationality. The 5 owners drink a certain type of drink, drive a certain type of car, and keep a certain pet. Using the clues below can you determine who keeps the wolves?

  1. The Pakistani lives in a red house.
  2. The Swede keeps dogs as pets.
  3. The American drinks lassi.
  4. The green house is on the immediate left of the white house.
  5. The green house owner drinks coffee.

  9. The Brit lives in the first house.
  10. The man who drives a Honda lives next door to the one who keeps cats.
  11. The man who keeps horses lives next door to the man who drives a Suzuki.

###Solution:

  1. Draw a table like this:

  2. Brit is the first and he lives next to the blue house.

  3. The middle house drinks Milk. (Sentence 8)

  4. Green is to the left of White (Sentence 3) so the only possibilities are 3,4 or 4,5. But Green cannot be at 3 because he drinks coffee (Sentence 5)

  5. Pakistani lives in a red house (Sentence 1) and the only column without a nationality and colour is 3rd.

  6. This makes 1st column yellow and the car a Suzuki (Sentence 7)

  7. The neighbour of the house with Suzuki keeps horses (Sentence 11)

  8. (Sentence 15) The man who drives a Honda has a neighbour who drinks water. One possibility is house 2.

  9. Bentley and Chocolate can only be together in house 5. (Sentence 12)

  10. Lassi is the only drink that’s left so House 2 is lassi and American (Sentence 3)

  11. The only house with an empty nationality and car is house 4, so house 4 must be Indian and BMW (Sentence 13)

  12. Now, only Swede is left and he keeps dogs (Sentence 2). We will also fill the car that’s left.

  13. The person who drives Toyota rears birds (Sentence 6)

  14. The man who drives a Honda lives next door to the one who keeps cats. (Sentence 10)

  15. Who keeps the wolves? Indian
