Zorluk: OrtaSeating Arrangement

Eight executives (A, B, C, D, E, F, G, and H) are attending a strategy meeting. They are seated in two parallel rows containing four seats each, with an equal distance between adjacent seats.

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.
Therefore, each person in Row 1 faces exactly one person in Row 2.

The following conditions are given:
1. D sits second to the left of the person who faces F.
2. F does not sit at any of the extreme ends of the row.
3. Only one person sits between A and C.
4. The person who faces C sits to the immediate left of H.
5. G sits to the right of E but not immediately.
6. B does not face E.

Based on the given seating arrangement, who sits second to the left of the person facing C?

  2. B
    H
  3. C
    A
  4. D
    F

Cevap

The correct answer is E.
Based on the fully deduced arrangement, C sits in Row 1 facing South. The person exactly facing C is G, who sits in Row 2 facing North. Because G faces North, G's left is toward the beginning of the row. The person sitting second to the left of G is E.

Adım Adım Çözüm

1
Analyze the basic row structure and facing directions.
Row 1 (South): A, B, C, D. Row 2 (North): E, F, G, H. Let the positions be 1, 2, 3, 4 from West to East (left to right from our perspective).
Establishing a standard coordinate system prevents left/right orientation errors.
2
Place F and D using conditions 1 and 2.
F is in Row 2 (North). F is not at an end, so F is at position 2 or 3. The person facing F is in Row 1 (South). D is second to the left of this person. For South-facing people, 'left' means moving East. If F is at position 3, the person facing F is at 3; second to their left would be position 5, which doesn't exist. Thus, F must be at position 2. The person facing F is at 2. Second to the left of position 2 is position 4. Therefore, D is at position 4 in Row 1.
This is the most restrictive starting point that firmly anchors two people.
3
Place A, B, and C in Row 1 using condition 3.
Row 1 currently has D at position 4. Empty seats are 1, 2, and 3. Since only one person sits between A and C, they must occupy positions 1 and 3. This leaves position 2 for B. So, B is at position 2, directly facing F.
Process of elimination for Row 1 positions based on spacing constraints.
4
Determine the exact positions of C and A using condition 4.
The person facing C sits to the immediate left of H (Row 2, North). If C were at position 1, the person facing C would be at position 1, meaning H would have to be at position 2. But F is already at position 2. Therefore, C cannot be at position 1. C must be at position 3 (making A at position 1). The person facing C is at position 3. Since this person is to the immediate left of H, H must be at position 4.
Testing the two possible locations for C against Row 2's constraints resolves the ambiguity.
5
Place E and G in Row 2 using condition 5.
Row 2 has empty seats at positions 1 and 3. G sits to the right of E but not immediately. Placing E at position 1 and G at position 3 satisfies this (they are separated by F at position 2). Checking condition 6: B (at 2) faces F, not E. All conditions are satisfied.
Fills the remaining seats in Row 2 and validates the final layout against the remaining rule.
6
Answer the specific question asked.
The question asks for the person sitting second to the left of the person facing C. C is at position 3. The person facing C is G (at position 3 in Row 2). G is facing North, so 'left' is West. Second to the left of G (position 3) is E (position 1).
Translating the final logical deduction into the required output.

Parallel Dual-Row Seating Arrangement

Alternatif Yöntem

You can visualize the problem by drawing two parallel horizontal lines and marking 4 tick marks on each. Label the top row 'S' (South) and the bottom 'N' (North). Draw arrows on the left/right ends of each line indicating standard left/right for North (L->R) and inverted right/left for South (R<-L). Filling the slots systematically from the most certain clue (F and D) guarantees no orientation mix-ups.
