Concentric Circles Arrangement
Concentric Circles Arrangement problems involve two or more circular rings where persons sit in inner and outer circles, typically facing the center. Persons in different circles may face each other across the rings. These problems test complex circular reasoning with multiple layers.

Concentric Circles Arrangement problems involve two or more circular rings where persons sit in inner and outer circles, typically facing the center. Persons in different circles may face each other across the rings. These problems test complex circular reasoning with multiple layers.
Prerequisites
How to Solve Concentric Circles Arrangement Problems
Step 1: Draw inner circle and outer circle with positions
Step 2: Note facing directions (typically both face center)
Step 3: Identify which positions face each other across circles
Step 4: Place definite positions in either circle
Step 5: Apply inter-circle clues: 'X faces Y' means aligned positions
Step 6: Apply within-circle clues using circular logic
Step 7: Fill remaining positions and verify
Example Problem
Example: Inner circle has 4 persons, outer circle has 6 persons (2 empty). All face center. A in inner circle faces B in outer circle. C sits opposite to A in inner circle. Who sits opposite to D in inner circle? Solution: Step 1: Inner circle positions I1-I4 clockwise, outer O1-O6 clockwise Step 2: A faces B → A and B aligned radially Step 3: C opposite to A in inner circle → C at opposite position Step 4: In 4-person inner circle, opposite pairs are I1↔I3, I2↔I4 Step 5: D opposite to someone determined by arrangement Answer: Person opposite to D in inner circle
