What is the profession of D ?
- (a) Judge
- (b) Stenographer ✓ UPSC's answer
- (c) Doctor
- (d) Cannot be determined
Why the answer is (b)
• The two married couples are A (engineer) with the lady stenographer, and the judge with the lawyer C.
• B is F's parent, so B is married; B is not A, so B must be in the judge–lawyer couple — B is the judge, married to C. This fits C being D's daughter-in-law, with D as B's mother and F's grandmother.
• Professions then run A engineer, B judge, C lawyer, E doctor, F draughtsman, which leaves D as the lady stenographer, married to A.
• Hence D is the stenographer — option (b).
Why the other options are wrong
- (a) Judge
- B is the judge.
- (c) Doctor
- E is the doctor.
- (d) Cannot be determined
- D's profession is fixed as stenographer.
