# Finding the minimum number of selections .

Lets assume I have three boxes that contains only apples, only oranges and a mix of apples and oranges respectively and all of them are mislabelled . What is the minimum number of selections that I need to make so that I can be certain which box contains what fruits assuming I can pick one fruit at a time from any of the boxes ?

P.S: It is not a homework task . So don't put that tag in here . I was asked this in an interview. I was looking for a interview tag but couldn't find one .
