Difficulty: HardSeating Arrangement

Eight executives—K, L, M, N, P, Q, R, and S—are seated in two parallel rows of four members each for a strategic meeting.

Members in Row 1 (P, Q, R, and S) are facing South.
Members in Row 2 (K, L, M, and N) are facing North.
Each executive in Row 1 sits exactly opposite to and faces one executive in Row 2.

The seating arrangement follows these conditions:
1. P sits second to the right of Q.
2. The executive facing Q sits to the immediate right of K.
3. M sits at one of the extreme ends of the row and does not face Q.
4. R sits to the immediate right of P.
5. N is an immediate neighbor of M.

Based on the above arrangement, which of the following statements is true?

  1. S faces the executive who sits to the immediate left of L.Answer
  2. B
    R faces the executive who sits to the immediate right of N.
  3. C
    Q sits second to the right of P.
  4. D
    L sits adjacent to the executive who faces P.

Answer

The statement 'S faces the executive who sits to the immediate left of L' is true.
Based on the deductions, Row 1 (South) from left to right is R, P, S, Q. Row 2 (North) from left to right is M, N, K, L. The executive sitting to the immediate left of L (who faces North) is K. The executive facing K is S. Therefore, the statement accurately describes the arrangement.

Step-by-Step Solution

1
Determine the layout of Row 1 (South-facing) using conditions 1 and 4.
Row 1 left-to-right (viewer's perspective) is R, P, S, Q.
Since Row 1 faces South, their 'right' is the viewer's left. P sits second to the right of Q means Q is at position 4 and P is at position 2. R sits to the immediate right of P places R at position 1. The remaining seat (position 3) belongs to S.
2
Locate K in Row 2 (North-facing) using condition 2.
K sits at position 3 (viewer's perspective).
Q is at position 4, so the executive facing Q is also at position 4. This person sits to the immediate right of K. Since Row 2 faces North, K must be at position 3 for position 4 to be its immediate right.
3
Place M and N in Row 2 using conditions 3 and 5.
M is at position 1 and N is at position 2.
M is at an extreme end (position 1 or 4) but does not face Q (who is at 4). Therefore, M is at position 1. N is M's immediate neighbor, placing N at position 2.
4
Complete Row 2 and evaluate the options.
Row 2 left-to-right is M, N, K, L. Evaluating the correct option: L is at 4, immediate left is K (at 3), and S (at 3) faces K.
L is the only remaining executive for position 4. Checking the valid spatial relationships against the options proves only one statement is factually accurate.
