Explanation : Here in given question there are three boxes incorrectly labeled:
.Box 3 – labeled as Apples and Oranges – Original Content can be Apple or Orange (This box will have only one fruit, so whichever we pick would be the correct label). Let’s say the picked item was Apple, therefore the box labeled Orange will have Apples and Oranges.)
.Box 2 – Oranges – This box will definitely not have orange (as its mislabeled) and it can not contain only apple (As it is in box 3) – So this will have Original Content- both oranges and Apples
.Box 1 – Apples – This is the leftover box and it can now have Original Content – Orange
