Directions : Study the following information carefully to answer the given questions:

Ten family members are sitting in two parallel rows containing five people each, in such a way that there is an equal distance between adjacent persons. In row–1 A, B, C, D and E are seated and all of them are facing north. In row-2 P, Q, R, S and T are seated and all of them are facing south. Therefore, in the given seating arrangement each member seated in a row faces another member of the other row.
P faces the one who sits 2nd to the left of his nephew. One person sits between P’s nephew and P’s mother. A is the sister-in-law of D who is not married. S is the granddaughter of B who sits left of P’s mother but not just left. R is the only brother of D who is the only immediate neighbour of B’s wife. Q is the husband of S and sits 2nd to the right of R’s father. A is the daughter of E and faces to the one who sits 2nd to the right of Q’s wife. P is the brother-in-law of R who is the father of C. T’s son sits just right of C’s brother-in-law. A’s father-in-law sits at one of the extreme ends. Both D and A are of same gender but opposite to C’s gender. B is not father of R.

Which of the following statement is true?

  1. A.

    A is the P’s spouse

  2. B.

    A’s father-in-law and E’s husband sits diagonally opposite to each other

  3. C.

    Two persons sit between D’s brother and Q

  4. D.

    S is sister of D

  5. E.

    None is true

Show answer & explanation

Correct answer: B

Concept

This item layers a blood-relation puzzle on a two-parallel-rows seating puzzle. Solve it in two passes: first build the family tree from the relationship statements alone (ignore the seats), then fix the seats from the positional statements. Row-1 faces north and Row-2 faces south, so each row's own left/right is defined from that row's own point of view — Row-1's own left-to-right runs the same way the layout is normally drawn, but Row-2's own left-to-right runs the OPPOSITE way across the same drawn columns (its own seat 1 is the drawn column at the far end from Row-1's seat 1). Two people who sit in the same drawn column face each other directly; the two ends at opposite drawn corners are diagonally opposite.

Step 1 — Build the family tree

  1. A is the sister-in-law of D, and D is unmarried; R is D's only brother. A married into the family through D's brother, so A is R's wife.

  2. A is the daughter of E, and P is R's brother-in-law (P is A's brother). So E is the mother of both A and P.

  3. B is E's husband, so B and E are a couple; A and P are their children.

  4. R is the father of C. A and R's children are C and S, which makes C and S grandchildren of B and E — matching “S is the granddaughter of B.”

  5. R and D share a father, T, so A's father-in-law is T. Q is the husband of S.

  6. D and A share one gender, opposite to C's, so A and D are female and C is male; S (C's sister) is female too. A “nephew” is by definition male, so P's nephew must be C, not S.

Step 2 — Fix the seating

Number Row-1's seats 1–5 from its own left to its own right (matching the drawn layout). Number Row-2's seats 1–5 from ITS own left to its own right too — but since Row-2 faces the opposite way, its own seat n sits in the SAME drawn column as Row-1's own seat (6−n): Row-2's own seat 1 lines up with Row-1's own seat 5, own seat 2 with Row-1's own seat 4, and so on.

  1. A's father-in-law (T) sits at an extreme end of Row-2 — take this as Row-2's own seat 1.

  2. Q sits two places to the right of T in Row-2's own numbering: Q is Row-2's own seat 3.

  3. R (T's son) sits immediately to the right of Q, who is S's husband and therefore C's brother-in-law (S is C's sister): R is Row-2's own seat 4.

  4. One person sits between C and his grandmother E: in Row-1's own numbering this fixes C two places to E's left.

  5. P faces the person sitting two places to the left of his nephew C (Row-1's own numbering): that person is B, at Row-1's own seat 1. Since C sits two places to the left of E in the same row, the only fit within seats 1–5 is B=1, C=3, E=5 — P must sit in the same drawn column as B (drawn column 1).

  6. Row-2's own seat 5 is the one that shares B's drawn column (own-seat n ↔ Row-1's own seat 6−n, and 6−5=1), so P is Row-2's own seat 5, leaving Q's wife S the one seat left over — Row-2's own seat 2.

  7. A faces the person two places to the right of Q's wife S (Row-2's own seat 2): that is Row-2's own seat 4, which is R — so A shares R's drawn column. R's own seat 4 sits in Row-1's drawn column 6−4=2, so A is Row-1's own seat 2, leaving D the one Row-1 seat left over, seat 4.

Every seat is now forced by the chain above, so this is the only arrangement consistent with all the clues:

Row

1

2

3

4

5

Row-1 (facing North)

B

A

C

D

E

Row-2 (facing South)

P

R

Q

S

T

Step 3 — Cross-check the statements

A's father-in-law is T, at Row-2's drawn column 5 (an extreme end); E's husband is B, at Row-1's drawn column 1 (the opposite extreme end). Two people at opposite drawn corners of the two rows are diagonally opposite — so the statement “A's father-in-law and E's husband sit diagonally opposite to each other” is the one that holds, and every other listed statement fails against this same fixed arrangement.
