The author of this problem is Albert Einstein who said that 98% of the people in the world couldn't solve it.

1. There are 5 houses (along a street) in 5  different  colors:

       Blue Master,  Dunhill,  Pall Mall,  Prince  and  blend;
and keep a certain pet:
       cat,  bird,  dog,  fish  and  horse.
4.  No  owners have the  same pet, smoke the same brand of  cigar, or drink the same  beverage.
