Maths And Reasoning Short Tricks: Reasoning Seating Arrangement Short Tricks

Today I am going to share technique to share seating arrangement (sitting arrangement) question sets.

# Cases of Seating Arrangement

Circle

Square

Rectangle

Lines

# Solving Seating Arrangement

Circle is the most important case from the exam point of view. Most of the times Circle kind of statements are there in exams.

From the exam point of view ,In most cases they give 8 person sitting in the circle.

But Before Solving the important thing is their ' Sitting position '.

Step 1 . Knowing NEWS! N= North , E= East , W=West , S= South

To remember this just remember combination ' North - South ' & ' West - East ' which comes together to each other respectively.

So remember " WE are Not Smokers" for combination

Now just place like this on paper

Step 2 : Picking Left & Right .

Facing Center

Facing Outside

If It is mention in the statement that all is facing outside then just do opposite of above like this:

Clock wise = Right & Anti- clock wise = Left

Step 3: Solving Step Wise the statement or Following the statement

Example :

Eight people E, F, G, H, J, K, L and M are sitting around a circular table facing the center. Each of them is of a different profession Charted Accountant, Columnist, Doctor, Engineer, Financial Analyst, Lawyer, Professor and Scientist but not necessarily in the same order. F is sitting second to the left of K. The Scientist is an immediate neighbor of K. There are only three people between the Scientist and E. Only one person sits between the Engineer and E. The Columnist is to the immediate right of the Engineer. M is second to the right of K. H is the Scientist, G and J are immediate neighbor of each other. Neither G nor J is an Engineer. The Financial Analyst is to the immediate left of F. The lawyer is second to the right of the Columnist. The Professor is an immediate neighbor of the Engineer. G is second to the right of Charted Accountant.

Before solving remember

No of Persons = 8 , No of Profession = 8
Facing Center
8 persons → 8 profession

Persons	Professions
E
F
G
H
J
K
L
M

Step 4 : Break statement into Shortcuts

Statement: F is sitting second to the left of K.
We can write it as:

[ Note : The Above diagram shows that there is one place vacant between F & K ]

Will get like this:

Step 5. Applying these Shortcuts into Circle Diagram

Be careful while positioning or placing Scientist and Engineer. There you need to make two diagram for each.

Step a) Pick any place and place it there the one person whom you want to be placed.

(Be careful while choosing that particular person or element like here E, F,G,H,J,K,L,M,N )

The one person or element you choose, should be relate with at least 2 element of the statement because it will make the other step easy for you. Try to choose the co-relating element which help you to fill the maximum space or seats or corners or places and Always choose the one in which you know the exact location (Left or Right).

Now here i choose F. F relates with K and M

[Note: Don't go again & again for reading whole statement, just use the shortcuts that you have made ]

Step b) Now check whether the already placed element co-relate with any other elements. like here

The Scientist is an immediate neighbor of K. So here is the relation between K & Scientist. Now here we don't know the exact position of Scientist. So Most of cases you will find this kind of problem. When there is a two possibility then it is Called ' T ' point.

Step c) Find whether there is any T point in a statement. Solve it by making two different diagram. Like here 1(a) & 2(a) which will further be checked whether these diagram satisfied the other problems or condition or statement given in the question. If it is not then make other two diagram. Like Here (1b & 2b). At the end , you will get the answer.
