Zorluk: OrtaSeating Arrangement

Eight architects—Harper, Ingram, Jenkins, Knox, Larson, Miller, Novak, and Ortiz—are sitting in two parallel rows containing four people each, such that there is an equal distance between adjacent persons.

In Row 1, Harper, Ingram, Jenkins, and Knox are seated, and all of them are facing South.
In Row 2, Larson, Miller, Novak, and Ortiz are seated, and all of them are facing North.
Therefore, each person in Row 1 faces a person in Row 2.

The following information is given about their seating arrangement:
- Jenkins does not sit at an extreme end of the row.
- Harper sits second to the left of Jenkins.
- Larson faces Harper and sits to the immediate right of Ortiz.
- Novak sits at one of the extreme ends of the row but does not face Jenkins.
- Only one person sits between Miller and Larson.
- Ingram faces Novak.

Based on the given arrangement, who sits to the immediate left of Knox?

  1. HarperCevap
  2. B
    Jenkins
  3. C
    Ortiz
  4. D
    Miller

Cevap

Harper
Based on the seating clues, Row 1 (South-facing) from viewer's left to right is: Ingram, Jenkins, Knox, and Harper. Knox is seated in the third position. Because he is facing South, his 'left' points toward the viewer's right. Therefore, the person sitting to his immediate left is Harper, who is in the fourth position.

Adım Adım Çözüm

1
Establish the directional framework for both rows.
Row 1 faces South (their left is our right). Row 2 faces North (their left is our left). Let's number positions 1 to 4 from our left to right.
Correctly orienting left and right based on facing direction is the most critical step to avoid inversion errors.
2
Place Jenkins and Harper in Row 1 using the first two clues.
Jenkins is at position 2 and Harper is at position 4.
Jenkins cannot be at extreme ends (1 or 4). Harper is second to the left of Jenkins. Since Row 1 faces South, 'left' means moving to our right. The only way Jenkins can have someone two spots to their left without being on an edge is if Jenkins is at position 2 and Harper is at position 4.
3
Place Larson and Ortiz in Row 2.
Larson is at position 4 and Ortiz is at position 3.
Larson faces Harper (position 4). Larson sits to the immediate right of Ortiz. Since Row 2 faces North, 'right' is our right, meaning Ortiz must be just left of Larson at position 3.
4
Place Miller and Novak in Row 2.
Miller is at position 2 and Novak is at position 1.
There is one person between Miller and Larson (position 4), forcing Miller to position 2. Novak is at an extreme end, leaving only position 1 open. Novak at position 1 does not face Jenkins (at position 2), satisfying the condition.
5
Complete Row 1 by placing Ingram and Knox.
Ingram is at position 1 and Knox is at position 3.
Ingram faces Novak (position 1). This leaves only position 3 for Knox.
6
Determine who sits to the immediate left of Knox.
Harper sits to the immediate left of Knox.
Knox is at position 3 facing South. His immediate left is our right, which is position 4. Harper occupies position 4.
