Circular Seating Arrangement
Overview
Description: People around a circular table.
Types:
Facing Center: Right = anticlockwise, Left 
= clockwise.
1.
Facing Outward: Right = clockwise, Left = 
anticlockwise.
2.
Mixed: Combine rules based on direction. 3.
Key Concepts
Directions: Depend on facing 
(center/outward).
Adjacency: Next to each other, not 
opposite.
Strategy: Use diagrams, make cases, 
eliminate.

Example
Pr o ble m: L, N, P , R, T, V, X, Z around a table, facing center, from states (Maharashtra, Assam, etc.). V is 2nd 
right of Kerala. Madhya Pradesh right of Kerala. N is 3rd right of Madhya Pradesh. T left of P . P , T not next to 
N or Gujarat (2nd right of R). R not Kerala/Madhya Pradesh. X next to Maharashtra. N not Maharashtra. 
One between P and Assam. Z 3rd left of Punjab. Delhi 2nd left of Karnataka.

Solution Steps
1
Read Carefully
Read the question carefully and note down the name or the characters that have to 
be arranged carefully.
2
Check Direction
Check and write down whether all the character is facing towards the centre or 
outwards or haphazardly some facing towards while others outward.
3
Draw Diagram
Now we will use diagrammatic representation to solve the question. Draw a circle 
with equidistant points and with the help of arrows signify the direction in which the 
characters are facing.
4
Apply Information
After this start reading the information and allot the places to the characters 
according to the information given in the question.
5
Make Cases
Make cases for multiple possibilities and then rule out those cases that don't fit the 
given information in the question.
6
Eliminate
Similarly go on deducing the cases and reach out to one possible case, which is the 
solution and eliminate all others.

Solution Implementation
1
Initial Setup
In the above example, we are given 8 alphabets each corresponding to 8 states. 
Representatives: L, N, P , R, T, V, X and Z States: Maharashtra, Assam, Gujarat, Kerala, 
Karnataka, Delhi, Madhya Pradesh and Punjab. We need to map representatives to 
their states, respectively.
2
Circle Creation
Now first we will make a circle with 8 equidistant lines and respectively add the 
direction in which the representatives are facing. Since all are facing towards the 
centre, everyone's right is in the anticlockwise direction and everyone's left is in the 
clockwise direction.
3
Direct Information
V sits second to the right of the representative from Kerala. A representative from 
Madhya Pradesh is to the immediate right of the representative from Kerala. N is 
third to the right of the representative from Madhya Pradesh.

Direct Information
V sits second to the right of the representative from Kerala. A representative from 
Madhya Pradesh is to the immediate right of the representative from Kerala. N is 
third to the right of the representative from Madhya Pradesh.
Placing Initial 
Elements
Here, we will first place V at the bottom-most place. 
We then place the representative from Kerala 
second to the left of V. This is because V sits second 
to the right of the representative from Kerala. Then 
we place the representative from Madhya Pradesh 
and N as given in the problem. So, we get the 
following figure.
