Money...
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.

A, B, and C have \$10 each. A, B and C give \$9 each to D. So D gets \$9x3 = \$27
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?
