Show answer & explanation
Correct answer: B
In a linear seating-arrangement puzzle, first place every person whose position is given directly (an end, a fixed seat), then use each adjacency ("neighbour of") or "sitting together" clue to fix the remaining people one step at a time, moving inward from the fixed anchors. In a row of 5 people, the middle seat is always the 3rd seat counted from either end.
Applying this to the given clues:
R is placed at the south end (seat 5) and S is placed at the north end (seat 1), since these positions are stated directly.
T is the neighbour of R, so T must occupy the seat next to R, which is seat 4.
T is also the neighbour of Q, so Q must occupy the seat on the other side of T, which is seat 3.
P and Q sit together, and the only seat left next to Q is seat 2, so P is placed at seat 2.
This places all five people: seat 1 = S, seat 2 = P, seat 3 = Q, seat 4 = T, seat 5 = R.
Seat | Person |
|---|---|
1 (North end) | S |
2 | P |
3 (Middle) | Q |
4 | T |
5 (South end) | R |
Checking every original condition against this seating: P and Q are adjacent, R is at the south end, S is at the north end, and T is adjacent to both Q and R — all four conditions hold, confirming this is the unique valid arrangement.
In a row of 5 seats, the middle (3rd) seat is occupied by Q — the correct answer.
