Show answer & explanation
Correct answer: A
Step 1: List the professions: Engineer, Doctor, Architect, Pharmacist, Lawyer, Journalist, Pathologist.
Step 2: Berths: 2 lower, 3 middle, 2 upper.
Step 3: A is an Engineer and not on upper berth. So A is on lower or middle.
Step 4: The Architect is the only other person with the same berth type as A. So A and Architect share a berth type, and no one else shares that type.
Step 5: B is Pathologist, not on middle. F is Lawyer, not on middle. So B and F are on lower or upper.
Step 6: C is Pharmacist.
Step 7: G is not Journalist or Architect.
Step 8: E occupies same berth type as Doctor.
Step 9: A and Architect share a berth type. Since A is not on upper, and only two people can be on upper, the shared berth type cannot be upper (because only two people can be on upper, and A and Architect would be two, but A is not on upper). So A and Architect are on lower or middle.
Step 10: B and F are not on middle, so they are on lower or upper. There are only 2 lower berths. If B and F are both on lower, that fills both lower berths. But A and Architect also need a berth type. If A and Architect are on lower, that would require 4 people on lower, impossible. So A and Architect cannot be on lower. Therefore, A and Architect are on middle.
Step 11: A and Architect are on middle. So middle berths are occupied by A, Architect, and one more person.
Step 12: B and F are not on middle, so they are on lower or upper. There are 2 lower and 2 upper berths. B and F must be on lower or upper.
Step 13: C is Pharmacist. C is not on middle (since middle has A, Architect, and one more). So C is on lower or upper.
Step 14: G is not Journalist or Architect. So G is one of Engineer, Doctor, Pharmacist, Lawyer, Pathologist.
Step 15: A is Engineer, so Engineer is taken. So G cannot be Engineer.
Step 16: B is Pathologist, F is Lawyer, C is Pharmacist. So remaining professions: Doctor, Journalist.
Step 17: G is not Journalist, so G must be Doctor.
Final Answer: G is a Doctor.
