Zorluk: KolaySeating Arrangement

Six family members—Arthur, Beatrice, Clara, David, Elena, and Felix—are sitting around a circular table facing the center for dinner.

The seating arrangement is based on the following conditions:
1. Arthur is sitting directly opposite David.
2. Beatrice is sitting immediately to the right of Arthur.
3. Clara is sitting exactly between David and Beatrice.
4. Elena is sitting immediately to the left of Arthur.

Based on this information, who is sitting immediately to the right of David?

  1. A
    Clara
  2. FelixCevap
  3. C
    Beatrice
  4. D
    Elena

Cevap

Felix
By successfully mapping the circular arrangement, all family members are placed. Since Felix is the only one left without an explicitly stated position, he takes the final empty seat. This seat is located immediately to the right of David, making Felix the correct answer.

Adım Adım Çözüm

1
Visualize or draw a circle with 6 equally spaced seats and place Arthur at one of the seats.
Arthur is assigned a position. For reference, let's place Arthur at the bottom (6 o'clock).
Setting a fixed starting point makes relative placements much easier.
2
Place David based on the first condition.
David is placed at the top (12 o'clock), directly opposite Arthur.
The condition states Arthur and David sit directly opposite each other.
3
Place Beatrice and Elena relative to Arthur.
Beatrice goes to the immediate right of Arthur (4 o'clock, counter-clockwise). Elena goes to the immediate left of Arthur (8 o'clock, clockwise).
Because everyone is facing the center, 'right' is counter-clockwise and 'left' is clockwise from the perspective of the person sitting.
4
Place Clara based on her position relative to David and Beatrice.
Clara is placed at 2 o'clock, which is the only seat exactly between David (12 o'clock) and Beatrice (4 o'clock).
The condition explicitly places Clara between these two specific family members.
5
Determine Felix's position and answer the final question.
Felix must occupy the last remaining seat at 10 o'clock. Since David is at 12 o'clock facing the center, his immediate right (counter-clockwise) is 10 o'clock, where Felix is sitting.
All other family members are placed. The question asks for the person to the immediate right of David.
