Passage beginning “A, B, C, D, E, F are members of…”

What is the profession of B ?

aJudge
bLawyer
cDraughtsman
dCannot be determined

AnswerUPSC’s answer is (a).

Match each person to a job. A is the engineer, C the lawyer, E the doctor and F the draughtsman, which leaves stenographer and judge for B and D. The judge is married to the lawyer C, who is D's daughter-in-law, so D, as C's mother-in-law, cannot be C's spouse. So B is the judge, married to C, and D is the stenographer, married to A. B is the judge.

Why each option is right or wrong
  • (a) Right. B is married to the lawyer C.
  • (b) C is the lawyer, not B.
  • (c) F is the draughtsman, not B.
  • (d) It can be determined from the clues.
