Who is the doctor ?
- (a) T ✓ UPSC's answer
- (b) P
- (c) Q
- (d) R
Why the answer is (a)
• Q is neither doctor nor artist, so Q is the lawyer.
• P and S are unmarried students, so they are not the married man's wife and do not hold the three professional roles.
• T is married to a group member other than P and S; Q is P's brother (male), so T's wife must be R.
• The doctor is not Q (lawyer), not R (stated) and not P or S (students), so T is the doctor; the remaining role, artist, goes to R.
• So: T – doctor, Q – lawyer, R – artist and T's wife; P and S are students.
• Hence the doctor is T, option (a).
Why the other options are wrong
- (b) P
- P is an unmarried student, not the doctor.
- (c) Q
- Q is neither doctor nor artist, so Q is the lawyer.
- (d) R
- R is stated not to be the doctor.
