Twenty Four Pigs In Four Pigpens
Put six pigs in the first pigpen, eight in the second, ten in the third, and nothing in the fourth. As you walk around the pigpens, you'll see that six is closer to ten than nothing, eight is closer to ten than six, ten is closer to ten than eight, and nothing is closer to ten than ten. (by Lewis Caroll)

The Missing Dollar
Each paid $10 for a total of $30. Then each got back $1, so each paid $9 for a total of $27 (27=30-3). Out of this $27, the inkeeper got $25 and the bellboy got $2 (27=25+2). Why should we then add the $2 the bellboy got to the $27 out of which it was paid?
