Zorluk: ZorSeating Arrangement

An executive committee of six professionals—Ramirez, Sato, Tanaka, Umar, Vance, and Wallace—are seated evenly around a circular boardroom table. They hold different roles: Director, Manager, Analyst, Planner, Coordinator, and Supervisor.

The Director, Analyst, and Coordinator are facing the center of the table. The Manager, Planner, and Supervisor are facing outward (away from the center).

The following conditions apply:
1. The Planner is seated adjacent to both the Director and the Supervisor.
2. The Analyst is seated at the immediate right of the Director.
3. Umar is the Planner.
4. Vance is seated exactly opposite the Supervisor.
5. Sato is positioned at the immediate left of the Manager.
6. Ramirez faces the center but is not the Coordinator.
7. Wallace does not sit adjacent to the Analyst.

Which of the following statements is logically correct based on the seating arrangement?

  1. Tanaka holds the position of Manager and sits exactly opposite Umar.Cevap
  2. B
    Vance is seated at the immediate left of Ramirez.
  3. C
    Sato is the Supervisor and sits adjacent to Wallace.
  4. D
    Wallace sits exactly opposite the Director.

Cevap

The statement identifying Tanaka as the Manager sitting opposite Umar is the only logically correct conclusion.
By logically deducing the seating order, we find that position 5 is occupied by the Manager, who is Tanaka. Position 2 is occupied by the Planner, who is Umar. In a 6-seat circular arrangement, positions 2 and 5 are exactly opposite each other, making this statement entirely true.

Adım Adım Çözüm

1
Determine the relative positions of the Director, Analyst, Planner, and Supervisor.
Let the Director be at position 1 (facing in). The Analyst is to the immediate right of the Director, placing the Analyst at position 6. The Planner sits between the Director and Supervisor, placing the Planner at position 2 and the Supervisor at position 3.
Since the Director faces inward, their right side goes counter-clockwise to position 6, forcing the Planner and Supervisor to occupy the clockwise positions.
2
Place the remaining roles based on facing directions and left/right rules.
Positions 4 and 5 must belong to the Coordinator (faces in) and Manager (faces out). Sato is at the immediate left of the Manager. If the Manager is at position 5 (facing out), their left is position 4. Thus, Manager is at 5 and Coordinator (Sato) is at 4.
If the Manager were at position 4, their left (facing out) would be position 3, which is already occupied by the Supervisor.
3
Assign the names to the established role layout.
Umar is the Planner (pos 2). Vance is opposite the Supervisor (pos 3), so Vance is the Analyst (pos 6). Ramirez faces the center (Dir, Ana, or Coo) but is not the Coordinator; since Vance is the Analyst, Ramirez is the Director (pos 1). Wallace cannot be next to the Analyst (pos 6), so Wallace is the Supervisor (pos 3), not the Manager (pos 5). This leaves Tanaka as the Manager (pos 5).
Applying the negative constraints and opposite pairings systematically fills the remaining seats without ambiguity.
