This creates complexity as left/right interpretations differ based on each person's facing direction. These problems test your ability to handle multiple perspectives simultaneously.
Prerequisites
How to Solve Linear Mixed Facing Directions Problems
Step 1: Draw positions 1 to n (viewer's left to right)
Step 2: Mark facing direction of each person when known (↑ for North, ↓ for South)
Step 3: For each clue, identify the speaker's facing direction first
Step 4: Translate the clue: if speaker faces North, their right = viewer's right; if South, their right = viewer's left
Step 5: Place definite positions and directions
Step 6: Use relative clues to deduce positions of others
Step 7: Fill remaining positions and verify all conditions
Example Problem
Example: Six persons P,Q,R,S,T,U sit in a row. Some face North, some South. P sits third from left facing North. Q sits second to right of P and faces opposite direction. Who sits between P and the person at left extreme? Solution: Step 1: Positions: 1,2,3,4,5,6 Step 2: P at position 3, facing North (↑) Step 3: Q second to right of P: from position 3, second right = position 5 Step 4: Q faces opposite to P (North) → Q faces South (↓) Step 5: Persons between P (pos3) and left extreme (pos1): position 2 Step 6: The person at position 2 is between them Answer: Person at position 2
