Prerequisites
How to Solve Three Parallel Rows Problems
Step 1: Draw three parallel rows with positions 1 to n
Step 2: Label facing directions: Row 1 (facing Row 2), Row 2 (facing Row 1 and Row 3), Row 3 (facing Row 2)
Step 3: Note: Person at position i in Row 1 faces person at position i in Row 2; Row 2 faces Row 3 similarly
Step 4: Place definite positions using facing relationships
Step 5: Apply within-row relative clues using appropriate facing logic
Step 6: Use chain relationships to transfer information across rows
Step 7: Fill remaining positions and verify
Example Problem
Example: Three rows with 3 chairs each. Row 1 faces South, Row 2 faces North, Row 3 faces South. A in Row 1 faces B in Row 2 who faces C in Row 3. D in Row 1 sits to left of A. Who sits at right extreme of Row 3? Solution: Step 1: Draw rows with positions 1,2,3 (left to right) Step 2: A faces B faces C → same position number for all three Step 3: Let them be at position 2 (center) Step 4: D left of A in Row 1 → D at position 1 Step 5: Remaining persons fill other positions Step 6: Right extreme of Row 3 is position 3 Answer: Person at Row3 position 3
