Interpreting the question as flu does: "What is the minimum number of fruit you need to draw (if you're lucky) where it could be possible to determine which all the jars are?"
The answer to that question is
Draw one fruit from each of the jars that says "mango" anywhere on its label, and they all just happen to be mangoes. Thus these three jars must be mixed with each other and the other three mixed among themselves.
Draw one fruit from the jar labeled just "mangoes", and get an orange. Now you know: "Mangoes" contains mangoes & oranges. "Mangoes & Apples" must be mislabeled, so it must contain just "Mangoes", and "Mangoes & Oranges" must contain mangoes & apples.
Draw one fruit from the box labeled "Apples & Oranges", getting an apple. That box must be labeled wrong, so it must be just apples, while "Oranges" must contain apples & oranges, and "Apples" must contain oranges.
Total: 5 fruit: 3 mangoes and an apple and an orange.
