Problem Analysis: Professions and Persons

We are given seven persons (A, B, C, D, E, F, G) and seven distinct professions. We need to find who among the options could be working as a PO based on the given constraints.

Initial Assignments and Constraints

• Known Professions: C works as a Clerk. F works as an IT Officer.
• Explicit Exclusions:
  • A cannot be an Economist or a Doctor.
  • E cannot be an Economist or a Doctor.
  • B cannot be a Driver, Economist, Doctor, or PO.
  • D cannot be a Doctor or PO.

Deductions for PO Role

Let's identify the potential candidates for the PO role:

• The PO is not C (Clerk) or F (IT Officer).
• B cannot be the PO (given constraint).
• D cannot be the PO (given constraint).

This leaves A, E, and G as the only possible candidates for the PO position.

Evaluating Option A as PO

We need to check if a valid profession assignment exists where A works as a PO. Let's assume A is the PO:

• Assigned: C = Clerk, F = IT Officer, A = PO.
• Remaining Persons: {B, D, E, G}
• Remaining Professions: {Economist, Doctor, Lawyer, Driver}

Now apply the remaining constraints:

• B cannot be Driver, Economist, or Doctor. Since PO, Clerk, and IT Officer are taken, and Lawyer is the only remaining option, B must be the Lawyer. (B = Lawyer)
• E cannot be an Economist or Doctor. Since Lawyer is taken by B, and PO, Clerk, IT Officer are assigned, E must be the Driver. (E = Driver)
• D cannot be a Doctor. Since Driver and Lawyer are assigned, and PO, Clerk, IT Officer are taken, D must be the Economist. (D = Economist)
• This leaves G to be the Doctor. (G = Doctor)

This scenario (A=PO, B=Lawyer, C=Clerk, D=Economist, E=Driver, F=IT Officer, G=Doctor) satisfies all conditions.

Since we found a valid scenario where A can be the PO, A is a possible candidate.

Final Check of Options

The options provided are G, A, D, B.

• We deduced B cannot be the PO.
• We deduced D cannot be the PO.
• We successfully constructed a scenario where A can be the PO.

Therefore, A could be working as the PO.
