Bill,George,Sally and Ann are brothers and sisters.I don't know how old each of them is.I only know that one of them is 18,one is 15,one of the boys is 16 and one of the girls is 17.I also know that Bill is older than Sally but Ann isn't.How old is Ann?How old is Bill?How old is George?How old is Sally?

bill is 18
george is 16
ann is 15
sally is 17

Bill :18
Ann:15
Sally:17
George:16
(tips:Bill,George are boys;Ann and Sally are girls).

“Bill is older than Sally but Ann isn't ”,而“one of the boys is 16 and one of the girls is 17”，所以Bill 最大18，另外一个 boy 就是 George 16，“but Ann isn't” ，说明Sally 比Ann大，就是17，剩下的 Ann 就是 15 了。首先要知道 Bill,George 是 boy ，Sally ，Ann 是 girl 。
