On a train, Smithe, Robins, and John are the fireman, conductor, and the engineer, but NOT respectively. Also aboard the train are three businessmen who have the same names: a Mr. Smithe, a Mr. Robins, and a Mr. John.
Mr. Robins Lives in New York.
The conductor lives exactly halfway between Columbus and New York.
Mr. John earns exactly $20,000 per year.
The conductor's nearest neighbor, one of the passengers, earns exactly three times as much as the conductor.
Smithe beats the fireman in billiards. The passenger whose name is the same as the conductor's lives in Columbus.
Who is the Engineer?

Answer by K Sengupta)
The conductor lives between New York and Columbus but Mr. Robins lives in New York. Hence, Mr. Robins cannot be the conductor's neighbor.
Mr. John earns $20,000 which does NOT correspond to a multiple of 3. Therefore, he cannot be the conductor's neighbor.
Therefore, Mr. Smithe must be the conductor's neighbor, Hence, it follows that Mr. John is the passenger who lives in Columbus. Hence, it follows that Mr. John is the passenger who lives in Columbus. Accordingly, the conductor must be John. The fireman cannot be John or Smithe, hence he is Robin's.
Consequently, the Engineer must be Smithe.
