How can you label the boxes correctly?

Answer 1

orange and apple is the answer

Answer 2

First, I would ask you to choose the box labelled "apples and oranges" (which actually doesn't contain both apples & oranges) and the fruit you pick up is going to be its label. Now you have an unlabelled box and wrongly labelled box and a free label. So what you're gonna do is take the label out of wrongly labelled box and put it on unlabelled box then put the free label on wrongly labeled box.
