Determine what each of the boxes contains ?

Question

Ravi has three boxes with fruits in his barn: one box with apples, one box with pears, and one box with both apples and pears. The boxes have labels that describe the contents, but none of these labels is on the right box.How can Ravi determine what each of the boxes contains, by taking only one piece of fruit from one box?

Answer 1

From the box named "mixture" , he can pick out a fruit and find what it contains.

Case 1: Say he picked out apple from it, then the box named pair would contain mixture (as it cannot contain pair because the box is named wrong) and the one named apple would contain pair.

Case 2: If he picked a pair from it, the box named apple would be mixture, and the one named pair would contain apple.
