Three boxes are labeled "Apples", "Oranges", and "Mixed". Every single box is incorrectly labeled. You may reach into one box without looking and pull out one piece of fruit. Which box should you pull fruit from to correctly identify the contents of all three boxes?
The box labeled "Mixed"
Since all boxes are incorrectly labeled, the box labeled "Mixed" must contain either only apples or only oranges. If you pull an apple from it, that box is the "Apples" box. The box labeled "Oranges" cannot be oranges, nor can it be apples (which you just located), so it must be "Mixed". The remaining box labeled "Apples" must then be "Oranges". The same deduction works if you pull an orange.
