GovernmentAdda has uploaded the Linear sitting arrangement  shortcut methods, Tricks & Rules and Questions with Answers here. Candidates can check and go through it. Coding and decoding tips are very useful to those who are preparing for the attending the bank exam IBPS, SBI, LIC AAO, UPSC, IAS, CAT, XAT, MAT, SSC, GATE, and other competitive exams. We have also published the Solved examples for the coding and decoding aptitude.

Linear sitting arrangement  is one of the most important topic in reasoning section of any competitive exams. We can expect 5-6 questions from this section.

General Guidelines to solve Linear sitting arrangement

1. First of all take a quick glance on the given information, After performing  this step , you would get an idea  of the situation of people.

3. when the place of any person or object is definitely  mentioned we can say that it is definite information  , Eg-  B is sitting on the right end of bench

4. when the place of any person or object is not mentioned definitely but mentioned in comparison of other person , we can say it is comparative information. eg-  B is sitting second right of C

5. A part of definite information may consists of negative information . A negative information  does not tell anything  but it gives an idea of to eliminate  a possibility . Eg- C is   not sitting immediate right of D

Types of Linear Sitting Arrangement

1. one row sequence

a ) When direction of face is not clear, then we take our self as base and then the diagram will be as follows :-

From the above diagram it is clear that :-

• B, C ,D, E are right of A but only B is to the immediate right of A.
• D, C ,B .A  are left of E but only D is to the immediate left of E.
• C , D, E  are  right of B  only C is immediate right of B
• C is in the middle of line .
•  A and E are sitting at the extreme end of line .

b) When direction of face is towards you, then the diagram will be as follows :-

From the above diagram it is clear that :-

• B is immediate left of A,
• C is immediate left of B;
• D is immediate left of C
• E is immediate left of D.
• D is immediate right of E
• C is immediate right of D
• B is immediate right of C
• A is immediate right of B.

2. Two rows sequence

Let us see 6 persons seating in two rows.

From the above diagram, it is clear that :-
(i) A is sitting opposite S.
(ii) B is sitting opposite T.
(iii) C is sitting opposite U.
(iv) A and U are sitting at diagonally opposite positions.
(v) C and S are sitting diagonally opposite positions.

Example 1 :-

Five friends A, B, C, D, and T are sitting on a bench.
(1) A is sitting next to B.
(2) C is sitting next to D.
(3) S is not sitting with T.
(4) T is on the last end of the bench.
(5) C is on the 2nd position from the right.
(6) A is on the right of B and T.
(7) A and C are sitting together

Solution :-

Here, 4th and 5th sentences constitute definite information.

Comparative information are: 1st, 2nd, 6th and 7th sentences .

3rd is a negative information.

T _  _ C _

STEP 2 :-this is the time to look for the comparative informations that tell about T and C. Such informations
are 2nd, 6th and 7th sentences. Take the 7th and the 1st sentence. If A and C are together and also B and A are together, then A must be between B and C. Now the arrangement take the form as:-

T B A C ____

STEP 3 :- By the virtue of the 2nd sentence:
T B A C D

Example 2 :-

P, Q, R, S, T, U, V and W are eight persons sitting in a row from left to right, not necessarily in the same order. All of them are facing towards North. T and Q are sitting adjacent to each other and neither of them is sitting adjacent to U.  Only S sits to the left of U. W sits neither adjacent to P nor to the left of P. T sits second to the right of W. V sits fourth to the right of U.

Solution :-

Step 1:- As only S sits to the left of U and V sits fourth to the right of U, we get

Step 2 :- Now, T sits second to the right of W and at the same time, W does not sit to the left of P. This implies that W and T can sit only in the following manner

Step 3:- Consequently, Q sits to the right of T as Q and T are sitting adjacent to each other and P sits at third position from the left in the row as P does not sit adjacent to W. Thus, the inal arrangement is shown below:-

NOTES:-

I. Sketch a diagram of empty places
II. Fill up as many empty  places as possible using all the definite informations.
III. With the help of comparative information consider all possibilities and select the possibilities which does not violate any condition
