Double Row Facing Each Other
Double Row Facing Each Other problems involve two parallel rows of persons where persons in one row face the other row. Typically, Row 1 faces South and Row 2 faces North, so persons in opposite rows face each other directly. These problems test your ability to coordinate two simultaneous linear arrangements.

Introduction to Double Row Facing Each Other
Double Row Facing Each Other problems involve two parallel rows of persons where persons in one row face the other row. Typically, Row 1 faces South and Row 2 faces North, so persons in opposite rows face each other directly. These problems test your ability to coordinate two simultaneous linear arrangements.
Prerequisites
How to Solve Double Row Facing Each Other Problems
Step 1: Draw two parallel rows with positions 1 to n (left to right)
Step 2: Label Row 1 (usually facing South) and Row 2 (facing North)
Step 3: Note: Person at position i in Row 1 faces person at position i in Row 2
Step 4: Place definite positions in either row
Step 5: Use cross-row clues: 'A faces B' means same position number
Step 6: Apply within-row relative position clues using appropriate facing logic
Step 7: Fill remaining positions and verify all conditions
Example Problem
Example: Two rows of 5 chairs each. Row 1 persons A,B,C,D,E face South. Row 2 persons P,Q,R,S,T face North. A sits at extreme end. P faces C who sits third from left. Who faces A? Solution: Step 1: Draw Row 1 (facing South) and Row 2 (facing North), positions 1-5 Step 2: A at extreme end → could be pos1 or pos5 Step 3: C third from left in Row 1 → pos3 Step 4: P faces C → P at Row 2 pos3 Step 5: A faces person at same position in Row 2 Step 6: If A at pos1, person at Row2 pos1 faces A Answer: Person at Row2 position 1
