谁是工程师之谜

确定已知事实。还要注意的是，乘客的头衔都是先生，而闸工、工程师和消防员都只写他们的姓。1.布朗先生住在纽约市。这个制车工住在纽约和芝加哥之间。琼斯先生每年正好挣2万美元。史密斯在最后一场高尔夫球比赛中打败了消防员。5.他的隔壁邻居是一名乘客，他的工资正好是他的三倍。6. The passenger who lives in Chicago has the same name as the brakeman. According to #1 and #2, the brakeman's neighbor cannot be Mr. Brown. According to #5, the brakeman's neighbor also cannot be Mr. Jones, because $20,000 is not evenly divisible by three. This leaves Mr. Smith as the next door neighbor to the brakeman. Mr. Smith lives halfway between New York and Chicago (#2) as does the brakeman. Since Mr. Brown lives in New York, by process of elimination, it is now known that Mr. Jones lives in Chicago. According to statement #6, this means that the brakeman is named Jones. According to statement #4, the fireman cannot be Smith, so the fireman must be must be Brown, which leaves Smith as the engineer. 你猜对这个谜语了吗?
