Kindly provided by Alex Bellos Photograph: Whit Preston/Getty Images Three friends (A, B and C) are playing ping pong. They play the usual way: two play at a time, the winner stays on, and the loser waits his/her turn again. At the end of the day, they summarise the number of games that each of them played:
A played 10 B played 15 C played 17. Who lost the second game?

A total of 21 games have been played ((10+15+17)/2) have been played.

In the second line of my answer, "the first" should be "the first or any odd-numbered". And the first line should have only one occurence of the phrase "have been played", not two.
