Three boxes are labeled 'Apples', 'Oranges', and 'Apples and Oranges'. Every single label is guaranteed to be incorrect. You are allowed to draw only one fruit from one box to figure out the correct labeling of all boxes. Which box should you pick from?
The box labeled 'Apples and Oranges'
Since all labels are wrong, the box labeled 'Apples and Oranges' must contain only apples or only oranges. If you draw a fruit from it and it's an apple, that box is 'Apples'. Knowing that, you can deduce the rest.
