- Harsh does NOT sit directly opposite Divya.
- Exactly 1 person sits between Aditi and Tarun in the same row.
- Divya sits immediately to the left of Aditi (both facing north).

- Aditi faces north.
- Lata sits immediately to the left of Farhan (both facing south).
Question: Determine the arrangement.
Reveal the answer
Answer: Row 1 (facing south): Tarun, Divya, Aditi. Row 2 (facing north): Farhan, Lata, Harsh.
- Start: 720 ways to seat 6 people in two facing rows of 3.
- Clue 5 — "Aditi faces north." narrows it to 360 possibilities. Board — North (W→E): _ · _ · _ | South (W→E): _ · _ · _
- Clue 2 — "Exactly 1 person sits between Aditi and Tarun in the same row." narrows it to 48 possibilities. Board — North (W→E): _ · _ · _ | South (W→E): _ · _ · _
- Clue 3 — "Divya sits immediately to the left of Aditi (both facing north)." ⇒ Aditi → the north-facing row, column 3 (1 = west), Tarun → the north-facing row, column 1 (1 = west), Divya → the north-facing row, column 2 (1 = west) (6 possibilities left). Board — North (W→E): Tarun · Divya · Aditi | South (W→E): _ · _ · _
- Clue 4 — "Harsh sits immediately to the left of Lata (both facing south)." narrows it to 2 possibilities. Board — North (W→E): Tarun · Divya · Aditi | South (W→E): _ · _ · _
- Clue 6 — "Lata sits immediately to the left of Farhan (both facing south)." ⇒ Farhan → the south-facing row, column 1 (1 = west), Harsh → the south-facing row, column 3 (1 = west), Lata → the south-facing row, column 2 (1 = west) (1 possibility left). Board — North (W→E): Tarun · Divya · Aditi | South (W→E): Farhan · Lata · Harsh
- Exactly one seating survives every clue — north row: Tarun, Divya, Aditi; south row: Farhan, Lata, Harsh.
How to crack double-row seating puzzles faster
- Treat each row as an independent linear arrangement, then apply the cross-row clues last.
- "Faces" means the person opposite — use these clues as cross-row constraints to lock both rows at once.
- Draw two parallel rows on paper, fill each row independently, then check which cross-row pairs satisfy the remaining clues.
- "Immediately to the left/right of" applies within the same row only — cross-row facing is a different relationship.

How do you solve double-row seating arrangement puzzles?
Solve each row independently first using linear-seating techniques, then apply cross-row constraints (facing, diagonally opposite) to find valid pairs. Draw two parallel rows and eliminate combinations that violate any clue.
