Brainteaser Answer 12:
Just One Box!
First, it’s important to note that ALL of the boxes are marked incorrectly…a lot of people miss that fact and thus get the wrong answer.
Let’s take a look…
You open the box marked BIG and it’s filled of the small eggs.
You know that the other two boxes must contain the big and mixed egg groups.
Those two boxes are marked SMALL and MIXED.
Now the box labelled MIXED must hold the big eggs because all boxes are labelled incorrectly.
Which leaves the SMALL box holding the big eggs.
…and all you had to do was open one box of eggs!
