Difficulty: EasySeating Arrangement

Four colleagues—David, Elena, Farah, and Greg—are sitting in a straight row facing a presentation screen (North). David is sitting at the extreme left end of the row. Elena is sitting to the immediate right of David. Greg is sitting at the extreme right end of the row. Arrange the colleagues in order of their seating positions from left to right.

  1. 1David
  2. 2Elena
  3. 3Farah
  4. 4Greg

Answer

The correct left-to-right order is David, Elena, Farah, and Greg.
Based on the given clues, David is at the extreme left (seat 1) and Greg is at the extreme right (seat 4). Elena is to the immediate right of David, placing her in seat 2. This leaves seat 3 for Farah. Therefore, the proper order from left to right is David, Elena, Farah, Greg.

Step-by-Step Solution

1
Identify the extreme ends of the row.
David is at position 1 (extreme left) and Greg is at position 4 (extreme right).
These positions are directly given in the initial clues.
2
Place Elena based on her relation to David.
Elena is placed at position 2.
The clues state that Elena sits to the immediate right of David, who is at position 1.
3
Place the final remaining person.
Farah is placed at position 3.
Positions 1, 2, and 4 are occupied. Position 3 is the only empty seat remaining for Farah.
