Truth in Packaging
Three boxes are all labeled incorrectly, and you must get the labels right. The labels on the boxes read as follows: [box 1] nails [box 2] screws [box 3] nails and screws To gain the information you need to move the labels to the correct boxes, you may remove a single item from one of the boxes. You may not look into the boxes, nor pick them up and shake them, etc. Can this be done? If so, how? If not, why not? |

first , assume all the boxes are in fact wrong. First draw from the (box 3) nails and screws. You will get either a nail or a screw. You will label it as which ever you draw out. Let's say it's a nail. So box3 is nails.Now the (box 1) nails can not contain nails so it must contain the screws. So box1 is labelled as screws. Box 2 is left which should contain both nails and screws . In short:
(box 1) screws (box 2) nails and screws (box 3) nails. |
