What is it that you would want the program to do?  Point out the flaw in 
the text?  This is an old "brain teaser" that uses a false statement to
confuse the listener.

Assuming that you're really asking what the answer is, then it's that they
didn't pay $27.  They paid $25 for the room, and the clerk "split" the 
change with them.  The hotel got $25, the clerk got $2, and they kept the
other $3.
