Truth in packaging


Best Answer Aaron Burr , 03 September 2007 - 04:15 PM

Perhaps?
The only way this works is to 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. The [box 1] nails can not contain nails so it must contain the screws. The [box 2] screws must there for be the mixture. In short:
[box 1] screws
[box 2] nails and screws
[box 3] nails

'No excuses!' We cannot shift that burden onto God, or nature, or the ways of the world Go to the full post

This will not work, as long as all the labels are indeed false. If they are, then if you pick up a nail from one of the boxes, it could be nails or nails and screws. same difference with the screws.

Pick something from the box labeled Nails and Screws.
What you find there tells you how to correct all the labels.
Did you think that through carefully? B))

Nope. [1] It doesn't obey the rules, and [2] it doesn't solve the problem.
[1] You may remove only one item from one box.
[2] You have to label all three boxes correctly.

incorrect labels--
[box 1] nails
[box 2] screws
[box 3] nails and screws


My logic is---

As ALL THREE boxes are labelled incorrectly, so, the correct combination can be (remember cyclic order?)--

combination 1:
[box 1] nails and screws
[box 2] nails
[box 3] screws

OR

combination 2:
[box 1] screws
[box 2] nails and screws
[box 3] nails

Now, ONLY BOX 3 can contain either screw or nail, but not both. So, pick up a sample from box 3, if it is a screw, Then use combination1 to label the boxes, otherwise (if nails), then use combination 2 to label it. So, the puzzle have two answers. Am I wrong?? :unsure:

I agree with storm you must have two solutions given that the box your opening has 2 different outcomes. B))

I got your point....there is only one method...but the box combinations can be two.....

not able. for you may find the box to put the right label on- or it could be the wrong- say you pick up a screw ok so maybe there are nails and you felt one as you picked up the screw- so you get that one right, but the other two are unknowned

Assuming the boxes are all labeled incorrectly, why not just remove the box itself. that way it doesn't matter witch box you open, you will still know how they should all be labeled.

Ex. Remove box # 2 and what ever spills out, you put the appropriate label, and move the only label that hasn't moved to the blank spot and move the origional label on box # 2 to the remaining box.
