Engineer
Written on 7:50 am by Vja Students
On a train, Sunil, Balaji, and Chaitu are the fireman, brakeman, and engineer, but not respectively. Also aboard there are three businessmen who have the same names: a Mr. Sunil, a Mr. Balaji, and a Mr. Chaitu.
1) Mr. Balaji lives in Delhi.
2) The brakeman lives exactly halfway between Chennai and Delhi.
3) Mr. Chaitu earns exactly Rs 20,000 per year.
4) The brakeman's nearest neighbor, one of the passengers, earns exactly three times as much as the
Brakeman.
5) Sunil beats the fireman at billiards.
6) The passenger with the same name as the brakeman lives in Chennai.
Who is the Engineer?
Ans: Sunil is the engineer
The brakeman's nearest neighbor can not be Mr. Balaji, since Mr. Balaji lives in Delhi and the brakeman is halfway from there to Chennai. The brakeman's nearest neighbor can not be Mr. Chaitu because 20,000 is not evenly divisible by 3. The brakeman's nearest neighbor is one of those 3 passengers, so he must be Mr. Sunil.The passenger with the same name as the brakeman lives in Chennai, and we know that Mr. Balaji and Mr. Sunil do not live in Chennai,so Mr. Chaitu must live in Chennai, so the brakeman must be Chaitu. So Sunil is either the fireman or the engineer, but since Sunil beats the fireman at billiards, he can not be the fireman, so he must be the engineer.
