Four cats live in the old grey house at the end of the road.  Their names are Puffy, Scruffy, Buffy, and Juniper.  Puffy has three times more whiskers than Juniper, but half as many as Scruffy.  Buffy has the same number of whiskers as the average number of whiskers on the three other cats.  If Juniper has 12 whiskers. how many whiskers does Buffy have?
If Juniper has 12 whiskers, then Puffy has 3*12=<<12*3=36>>36 whiskers.
Since Puffy has half as many whiskers and Scruffy, then Scruffy has 36*2=<<36*2=72>>72 whiskers.
Since the number of whiskers on Buffy is the average between 12, 36, and 72 whiskers, then he has (12+36+72)/3=40 whiskers.
