A little puzzle for you:

Three men buy a $30.00 item together, each paying $10.00

The seller realizes after they are gone that he should have only charged $25.00

But he doesn’t know how to split $5.00 3 ways. So he pockets $2.00 and gives

each man $1.00 back.

So each man paid $9.00

$9.00 X 3 = 27

27 + 3 = 30

BUT

the seller only pocketed $2.00

Where is the extra dollar?
