Sorry if this is too easy....:)
A, B, and C, have $10 each. They call D to buy snacks for them. The snacks cost them $25. A, B, and C each keeps 1$ of the change and give $2 to D.
Re-sum the money : A, B, and C spent $9 each and D got $2, so total money = 3 x $9 + $2 = $29
Well, the sum supposes to be $30, doesn't it? Where is the missing $1 ?
That does not make any sense.

D buys some snacks and pays $25 -> $27-$25 = $2 change.
So the $2 were included in in the $27. That's why $27 + $2 = $29 does not make any sense.
You know what I'm saying?
That puzzle has been around for years....
