Wrong Labels You are given three jars that contain gumdrops, candy-coated chocolate drops,
and the third jar has a combination mix of these. You
are told that every label is wrong on the jars, and the jars are not transparent. What is the
least number of candies you must test in order to re-label them correctly?
The answer is ONE: take a candy from the jar labeled "Mix" - you know this jar with the wrong lable is not mixed - so that is
the jar filled with the sweets you pulled out - say gumdrops. Now you know the jar labeled "Gumdrops" (which isn't gumdrops)
could be "Mix" or "Chocolate" - but since the other jar is wrongly labeled "Gumdrops" then the "Gumdrop" jar must have the
"Chocolates" (since the "Mix" jar has the gumdrops). Then the "Chocolate" jar must have the mix.
