Who is the Engineer?

Question

ON a train Smith, Jones, and Robinson are the fireman, brakeman, and engineer, but NOT respectivly.
Also aboard are three business men who have the same names: a Mr. Smith, a Mr. Jones, and a Mr. Robinson.
here are the clues:
1) Mr. Robinson lives in Detroit.
2) The brakeman lives exactly half between Detroit and Chicago.
3) Mr. Jones earns exactly $20,000 per year.
4) The brakeman's nearest neighbor,one of the passengers, earns exactly three times as much as the brakeman.
5) Smith beats the fireman at billiards.
6) The passenger with the same name as the brakeman lives in Chicago.

Answer 1

I really don't think you have enough information to solve the problem.

Smith cannot be fireman. (clue 5)
Robinson cannot be brakeman. (clue 1, clue 6)

So, if Smith is the brakeman, and Robinson is the fireman, then Jones is the engineer.

If Smith is the engineer, and Robinson is the fireman, then Jones is the brakeman.

If Smith is the brakeman, and Robinson is the engineer, then Jones is the fireman.

There are three possible solutions with the amount of information you have given. (Some of the information, such as the salary, was not useful at all.)
