Sitting Arrangement (बैठक व्यवस्था)
1. Direction Conventions & Step-by-Step Arrangement Rules
Establishing clear positional anchors prevents directional inversion and invalid layouts[cite: 5]:
- Linear Orientation (Facing North vs South): Facing North means Left = Page Left, Right = Page Right[cite: 5]. Facing South reverses Left and Right[cite: 5].
- Circular Orientation (Centre vs Outside): Facing Centre \(\implies\) Right is Anti-Clockwise, Left is Clockwise[cite: 5]. Facing Outside reverses these rotations[cite: 5].
- Conjunction "Who / Whom / Which" (जो / जिसे): Strictly qualifies the second person or immediate preceding entity ("A sits right of B, who is next to C" \(\implies\) B is next to C)[cite: 5].
- Conjunction "And / But / While" (और / लेकिन / जबकि): Strictly qualifies the first person of the clause ("A sits right of B and left of C" \(\implies\) A is left of C)[cite: 5].
- Opposite Seating Parity: In symmetric arrangements of \(2n\) members (6, 8, etc.), opposite positions are separated by \(n-1\) intervening seats; in odd configurations (5, 7 members), true diametric opposites do not exist[cite: 5].
2. Primary Structural Frameworks
- Linear Formats: Single or dual parallel rows with fixed endpoints or defined central nodes[cite: 5].
- Circular Formats: Symmetrical round tables with clockwise/anti-clockwise chains[cite: 5].
- Polygonal / Square Formats: Corner vs middle-edge seats with alternating inward/outward orientations[cite: 5].
3. Worked Examples & Deduction Formulas
- Middle Element in Linear Rows: In a row of \(N=5\) facing North, if \(B\) is at an end and \(3^{\text{rd}}\) to the left of \(D\), \(B\) must occupy position \(1\) and \(D\) position \(4\)[cite: 5]. If \(C\) is immediately left of \(E\), they form a block at \((2, 3)\)[cite: 5]. The arrangement is \(B(1) - C(2) - E(3) - D(4) - A(5)\), with \(E\) at the exact center[cite: 5].
- Opposites in a 6-Seat Circle: When 6 persons sit around a table at positions \(1\) through \(6\) clockwise, pairs \((1, 4)\), \((2, 5)\), and \((3, 6)\) face each other directly across the diameter[cite: 5].
