Zorluk: OrtaSeating Arrangement

Seven city council members—Higgins, Inez, Jenkins, Kline, Larson, Mosley, and Nunez—are seated around a circular conference table facing the center to discuss urban planning.

• Jenkins is an immediate neighbor of both Inez and Mosley.
• Larson sits third to the left of Mosley.
• Higgins sits second to the right of Jenkins and is an immediate neighbor of Nunez.

Based on the given information, who sits third to the right of Inez?

  1. HigginsCevap
  2. B
    Nunez
  3. C
    Mosley
  4. D
    Kline

Cevap

Higgins
Based on the deductive arrangement, the individuals are seated in the following clockwise order: Mosley, Jenkins, Inez, Larson, Kline, Nunez, and Higgins. Inez sits between Jenkins and Larson. Moving to the right (counter-clockwise) from Inez, the sequence passes Jenkins, then Mosley, and lands on Higgins. Therefore, Higgins sits exactly third to the right of Inez.

Adım Adım Çözüm

1
Establish the directional rules for a circular table.
Since everyone faces the center, 'left' means moving clockwise, and 'right' means moving counter-clockwise.
Correct left/right orientation is mandatory before placing any individuals.
2
Place Mosley and Larson based on the second clue.
Let Mosley be at position 1. Moving three spots clockwise (left), Larson is placed at position 4.
This establishes a baseline positional framework.
3
Analyze Jenkins' placement using the first clue.
Jenkins must be between Inez and Mosley. This gives two scenarios: (Scenario A) Inez=3, Jenkins=2, Mosley=1. (Scenario B) Inez=6, Jenkins=7, Mosley=1.
Adjacent relationships usually create two mirror possibilities that must be tested against further clues.
4
Test Scenario B against the third clue.
If Jenkins is at 7, second to his right (counter-clockwise) is position 5 for Higgins. But Higgins must be next to Nunez, and positions 4 (Larson) and 6 (Inez) are already full. Scenario B is invalid.
Contradictions eliminate incorrect layout branches.
5
Complete the arrangement using Scenario A.
Jenkins is at 2, Inez at 3. Second to the right of Jenkins (2) is position 7 for Higgins. Higgins is next to Nunez, so Nunez must be at position 6. Kline takes the remaining spot at 5.
This produces a single deterministic sequence (Clockwise 1 to 7): Mosley, Jenkins, Inez, Larson, Kline, Nunez, Higgins.
6
Answer the final question: third to the right of Inez.
Inez is at position 3. Moving right (counter-clockwise) three spots from 3 goes to 2, 1, and then 7. The person at position 7 is Higgins.
Applying the final query to the confirmed valid seating layout.
