Zorluk: ZorSeating Arrangement

Eight executives—A, B, C, D, E, F, G, and H—belong to eight different departments: HR, IT, Finance, Sales, Marketing, Operations, R&D, and Legal. They are sitting in two parallel rows containing four people each, with an equal distance between adjacent persons.

In Row 1: A, B, C, and D are seated, and all of them are facing South.
In Row 2: E, F, G, and H are seated, and all of them are facing North.
Each executive in a row faces exactly one executive from the other row.

Observe the following conditions:
1. E, who is from Marketing, sits at one of the extreme ends of the row.
2. The executive from Finance sits second to the left of the person who faces E.
3. Only one person sits between G and the executive from Legal.
4. F, who is from R&D, sits to the immediate right of G.
5. The person who faces the R&D executive sits to the immediate right of D, who is the Sales executive.
6. B is from IT and does not face the Marketing executive.
7. The Operations executive faces the IT executive.
8. C does not sit at an extreme end of the row.

Based on the arrangement, match the following executives with their correct department and seating characteristic:

  • Executive AHR Department - Faces the Marketing executive
  • Executive CFinance Department - Sits adjacent to the Sales executive
  • Executive GOperations Department - Faces the IT executive
  • Executive HLegal Department - Sits at the extreme right end of Row 2

Cevap

The correct pairings are: Executive A matches with 'HR Department - Faces the Marketing executive'; Executive C matches with 'Finance Department - Sits adjacent to the Sales executive'; Executive G matches with 'Operations Department - Faces the IT executive'; and Executive H matches with 'Legal Department - Sits at the extreme right end of Row 2'.
Based on the systematic deduction of the seating arrangement grid, the final layout from left to right is as follows:
Row 1 (South): A (HR), B (IT), C (Finance), D (Sales).
Row 2 (North): E (Marketing), G (Operations), F (R&D), H (Legal).
Matching the executives to their correct department and positional traits perfectly aligns with this derived matrix.

Adım Adım Çözüm

1
Determine the position of E and the Finance executive.
E (Marketing) is at Row 2, Position 1 (Left end). The Finance executive is at Row 1, Position 3.
E is at an extreme end of Row 2 (facing North). If E were at the right end (Pos 4), the person facing E would be at Row 1 Pos 4. For a South-facing person, 'left' is towards the viewer's right. The second to the left of Pos 4 would be off the grid. Thus, E must be at Pos 1. The person facing E is Row 1 Pos 1. The second left of Pos 1 (South-facing) is Row 1 Pos 3, which must be Finance.
2
Place G, F, and the Legal executive in Row 2.
Row 2 from left to right is: E (Marketing), G, F (R&D), and H (Legal).
F (R&D) is to the immediate right of G (facing North, so viewer's right). Only one person sits between G and Legal. Since E is at Pos 1, G must be at Pos 2 (making F Pos 3) or G at Pos 3 (making F Pos 4). If G is Pos 3, Legal would have to be Pos 1, which is impossible as E is there. Thus, G is Pos 2, F is Pos 3, and Legal is Pos 4. The only unplaced person for Row 2 is H, so H is Legal.
3
Place D (Sales) and B (IT) in Row 1.
D (Sales) is at Row 1 Pos 4. B (IT) is at Row 1 Pos 2.
The person facing F (R&D) is Row 1 Pos 3 (Finance). Finance sits to the immediate right of D (Sales). For South-facing people, right is the viewer's left. So D must be seated to the viewer's right of Pos 3, meaning D is at Pos 4. B (IT) cannot face E (Pos 1), so B must be at Pos 2.
4
Resolve the remaining individuals and departments.
Row 1 from left to right is: A (HR), B (IT), C (Finance), D (Sales). G is Operations.
C cannot sit at an extreme end, so C must be at Pos 3 (Finance), leaving A at Pos 1. The Operations executive faces IT (B at Pos 2), so G is Operations. The only unassigned department is HR, so A must be HR.
