Directions : Read the following information carefully and answer the following questions.
Eight persons A, B, C, D, P, R, S and Q are sitting around a circular table such that some of them face inside and some face outside. They all have different professions, viz. Banker, Writer, Singer, Doctor, Nurse, Dancer, Engineer and Teacher, but not necessarily in the same order. One person has only one profession. Not more than four persons face the same direction. The singer sits second to the right of Q. Three persons sit between A (who does not sit adjacent to the Banker) and the one who is the Nurse. D is an Engineer. P sits opposite to Q, who is a Banker. C is a female but she is not a dancer. The teacher and the writer face inside. The one who is the Brother of Q sits second to the right of the Banker. Two persons sit between S (who is a Doctor) and the brother of Q. D is the mother of Q and she sits opposite to S. D's daughter sits third to the left of D. A is the father of Q, who is a female. Both C and R are children of P, who is married to Q. B and R are the male members. B, who faces inside, sits opposite to the Dancer. The Writer sits second to the right of the Dancer. The Singer is married to the Doctor. S is the sister-in-law of Q. R does not sit immediate left of S.

Show answer & explanation
Correct answer: B
Concept: In a puzzle that mixes seating with blood-relation clues, first build the family tree using ONLY the direct relational statements (parent, spouse, child, sibling). The family tree never depends on where anyone sits; the seating clues are used afterwards, only to attach the leftover professions to the leftover people.
D is the mother of Q and A is the father of Q, so A and D are the married couple who are Q's parents.
Q is female and P is married to Q, so P is Q's husband (male).
C and R are the children of P (and therefore of Q); C is female and R is male, so C is the daughter and R is the son — both are D's grandchildren.
The clues name a 'Brother of Q', and the only male still unplaced in the family is B, so B is Q's brother — another child of A and D.
Now fix the professions. D is the Engineer and Q the Banker (both stated), and S is the Doctor (stated). The Singer is married to the Doctor S, and the only person free to be S's spouse is B; so B is the Singer, and since B is Q's brother, his wife S is Q's sister-in-law (this is exactly why the clue calls S Q's sister-in-law).
That leaves Writer, Nurse, Dancer and Teacher for A, C, P and R. Applying the seating clues — the Singer B faces inside two seats to Q's right and sits opposite the Dancer; the Writer sits two seats to the Dancer's right; the Teacher and Writer both face inside; A sits opposite the Nurse and not next to the Banker; and C is not the Dancer — yields exactly one valid arrangement: R is the Dancer, P is the Writer, C is the Nurse, and A is the Teacher.
So the Teacher is A. A is the father of Q and the husband of D, and D is the Engineer. Therefore the Teacher is the Engineer's husband.
