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.
How is R related to the one who sits exactly in the middle of the row-1?
- A.
Brother-in-law
- B.
Son
- C.
Father-in-law
- D.
Father
- E.
Son-in-law
Show answer & explanation
Correct answer: D
Concept
In a two-parallel-row puzzle, first lock every family role from the blood-relation clues, then seat people using the direction rule: for a north-facing row the person's left is the observer's left, while for a south-facing row the person's left is the observer's right. The relationship asked is then read straight off the completed family tree, never guessed from a seat label.
Application: build the family
D is unmarried and R is the only brother of D, while A is the sister-in-law of D. A married woman can be D's sister-in-law only as the wife of D's brother, so A is the wife of R.
R is the father of C and A is R's wife, so C is the child of the couple R and A.
A is the daughter of E, and P is R's brother-in-law as the brother of A, so E is the parent of both A and P.
The only married woman available as B's wife is E, so B and E are a couple and the parents of A and P. As A is their daughter, A's children are also grandchildren of B; so S, the granddaughter of B, is another child of R and A, that is a sister of C, and Q is the husband of S.
Because S is a sister of C, S's husband Q is the brother-in-law of C. The remaining person T is the father of R (Q sits second to the right of R's father), so T is the father of R and D.
Application: seat everyone
Apply the placement clues together: B sits to the left of E with a gap (not just left); exactly one person sits between C and E; P faces the seat second to the left of C; T sits at an extreme end; Q sits second to the right of T; A faces the seat second to the right of S; and the son of T sits just to the right of C's brother-in-law Q. Only one layout satisfies all of these at once.
Row | Seat 1 | Seat 2 | Seat 3 (middle) | Seat 4 | Seat 5 |
|---|---|---|---|---|---|
Row-1 (North) | B | A | C | D | E |
Row-2 (South) | P | R | Q | S | T |
Cross-check and result
The person in the exact middle of Row-1 is C. From the family tree, C is the child of R. Hence R relates to the person in the middle of Row-1 as stated by the keyed option.
