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?
Smith is the engineer.
Sol:1. Either Mr. Smith or Mr. John can live in Columbus.
2. As Mr. John's salary is not an exact multiple of 3, Mr. John lives in Columbus and Mr. Smith lives close to the conductor.
4. Smith cannot be the fireman, as Mr. Smith beats fireman.
5. John is the conductor, as Mr. John lives in Columbus.
6. So, Robins is the Fireman.
7. Thus, Smith is the engineer.
