In continuation with our article on Seating Arrangement which we posted , here we are posting some tricks to solve more complicated questions from the topic which are becoming very common in the recent Banking Exams.
In linear (row) arrangement problems, we have to arrange the data linearly. The arrangement is done only one “axis” and hence, the position of people or objects assumes importance in terms of order like first position, second position, last position. In this type of arrangement, we take directions according to our left and right.
There are two types of problems asked in competitive exams, from this topic.
- One Row arrangement – In one row arrangement problems, people or objects sits in a row either facing North or South. So, we have to make arrangement according to the direction of face of the people.
- Two Row arrangement – In two row arrangement problems, there are two groups of people or objects sits in a two rows and people sitting in a first row facing North or South and vice versa.
No matter what the model is, the following points are to be noted in order to solve the questions easily.
Read the entire information and understand the statements correctly
- Identify the statements that give definite information.
- For instance let us take three statements and evaluate them
One Row arrangement
Now, let us understand with the figure. Four people A, B, C, D are sitting in a row facing North direction.
From the above figure, we can draw these conclusions:
(i) A and D are sitting at the extreme end of the line.
(ii) Right of A = B, C, D.
(iii) Left of D = C, B, A
(iv) A is sitting immediate left of B. B is sitting immediate left of C. C is sitting immediate left of D.
(v) B is sitting immediate right of A. C is sitting immediate right of B. D is sitting immediate right of C.
(vi) A is sitting second to the left of C. B is sitting second to the left of D.
(vii) C is sitting second to the right of A. D is sitting second to the right of B.
(viii) A is sitting third to the left of D. D is sitting third to the right of A.
Four people A, B, C, D are sitting in a row facing South direction
From the above figure, we can draw these conclusions:
(i) A and D are sitting at the extreme end of the line.
(ii) Left of A = B, C, D.
(iii) Right of D = C, B, A
(iv) A is sitting immediate right of B. B is sitting immediate right of C. C is sitting immediate right of D.
(v)B is sitting immediate left of A. C is sitting immediate left of B. D is sitting immediate left of C.
(vi) A is sitting second to the right of C. B is sitting second to the right of D.
(vii) C is sitting second to the left of A. D is sitting second to the left of B.
(viii) A is sitting third to the right of D. D is sitting third to the left of A.
Two Row arrangements
Now, let us understand with the figure. Eight people are sitting in two parallel rows containing four people each in row, such a way that there is an equal distance between adjacent persons. In row 1, A, B, C, and D are sitting and all of them are facing South. In row 2, P, Q, R, and S are sitting and all of them are facing North.
From the above figure, we can draw these conclusions:
(i) A, D, and P, S are sitting extreme end of the line.
(ii) A is sitting opposite to P. B is sitting opposite to Q. C is sitting opposite to R. D is sitting opposite to S.
(iii) A and S is sitting diagonally opposite to each other.
(iv) D and P is sitting diagonally opposite to each other.
(v) B and R is sitting diagonally opposite to each other.
(vi) C and Q is sitting diagonally opposite to each other.
Solved Example (Based on One row arrangement problems)
Question (1) – Anil, Bobby, Charu, Deepak, Esha, Faizal, Gaurav and Harish are sitting in a row facing North.
(i) Anil is fourth to the right of Esha.
(ii) Harish is fourth to the left of Deepak.
(iii) Charu and Faizal, who are not sitting at extreme ends of the line, are nieghbours of Bobby and Esha respectively.
(iv) Harish is next to the left of Anil and Anil is the neighbor of Bobby.
STEPS TO SOLVE THE QUESTION
From the first information (i), we get that there are three persons between Anil and Esha.
In the information (iv), we get that Harish is next to the left of Anil and Anil is the neighbor of Bobby. Using the information (i) we get –
By the information (ii), Harish is fourth to the left of Deepak
By the information (iii), Charu and Faizal, who are not sitting at extreme ends of the line, are nieghbours of Bobby and Esha respectively.
So, we can assume Gaurav is sitting between Faizal and Harish.
So, Esha and Deepak is sitting at the extreme ends of the line.
Solved Example (Based on Two row arrangement problems)
Question (1) Eight members P, Q, R, S, T, V, H and L are sitting in two rows with equal number of members in each row. Members of one row are facing North and those in other row are facing South. Each member in one row is sitting exactly opposite a member in the other row.
(i) P sits in the row facing North, to the immediate right of H who is exactly opposite of R.
(ii) L is to immediate right of R and S is exactly opposite of T who is to the immediate right of P.
(iii) V does not sit at any of the ends any row.
STEPS TO SOLVE THE QUESTION
From the (i) information it is clear, that P and H is facing North and P is to the immediate right of H. R is facing South.
From the (ii) information, we get
From the (iii) information, we get
So, now only Q remains who is sitting one of the extreme ends of the line.

Points to Remember
The Meaning of and, who and adjacent in seating arrangement questions:
- If two information is joining by “and” , than the information is talking about the first person.
For e.g. – A is third to the left of B and second to the right of D.
Here it means – A is sitting third to the left of B and also A is sitting second to the right of D. Many student’s confuse here and take information as a – A is sitting third to the left of B and B is sitting second to the right of D, which is wrong.
- If two information is joining by “who”, than the information given after “who” is talking about the second person.
For e.g. – A is third to the left of B who is second to the right of D.
Here it means – A is sitting third to the left of B and B is sitting second to the right of D.
Many student’s confuse here and take information as a – A is sitting third to the left of B and also A is sitting second to the right of D, which is wrong.
- Adjacent – means – next to each other not opposite to each other. A and B is adjacent to each other, which means they are immediate neighbor of each other.
