Last week's challenge from American puzzlemaker Sam Lloyd: You have a target with six rings, bearing the numbers 16, 17, 23, 24, 39 and 40. How can you score exactly 100 points, by shooting at the target?
Answer: You get 16 rings twice, and 17 rings four times.

Next week's challenge: This challenge comes from Jason Zuffranieri, who competed for the U.S. at the World Puzzle Championship in London a week ago. Name a world leader of the 1960s — two words. Change the last letter of the second word. Then switch the order of the words — that is, putting the second word in front. The result will name a hit song of the 1990s. Who is the leader, and what is the song?
