Okay folks, its been a while since I've posted one of these of the logic type. So lets see whos clever enough!

There are three sealed envelopes. One contains two $5 bills, one contains a $10 and a $5 bill, and the third contains two $10 bills. Unfortunately, all three envelopes have the wrong amount marked on the outside. How could you correct all three by opening one envelope and looking only at one bill?

OPen the envelope marked $15.  If you pull out a $5, then you know that must be the envelope that is $10.  And since all are wrong, then the envelope marked $10 must be 20 and the one marked 20 must be 15.

If you pull out a 10, then that envelope must be 20, and the one marked 10 must be 15, and the one marked 20 must be 10.
