Riddles, brain puzzles and mathematical problems

[BAndrew]

I have solved it in the past (I think 2 years ago). It's too easy and boring. No thought required, you just have to be patient. I bet Einstein never wrote it. They just gave it this name to popularize the riddle. I don't like it at all. I won't post the solution so others can solve it.

Not to mention the vagueness some statements have. For example, in statement NO4 The green house is left of the white house, but from which perspective?
