Seating Arrangementबैठक व्यवस्था questions and answersप्रश्न और उत्तर

How seating arrangement worksबैठक व्यवस्था को समझिए

Start with the clues that pin someone down: “sits at an end”, “third from the left”. Then add neighbour clues (“immediately right of”), and finally the negative ones (“is not next to”).

When a clue allows two places, draw both rows and keep them until another clue rules one out. Most exam puzzles need only one or two such branches.

Facing north, a person’s right is your right. When people face south (or the centre of a circle), right and left change; read the direction line carefully.
