Linear Seating Arrangement MCQs with Answers and Detailed Explanations
Linear Seating Arrangement is one of the most important topics in Logical Reasoning for competitive exams. In this topic, candidates must determine the correct positions of people or objects arranged in a straight row by carefully analyzing the given clues. Mastering Linear Seating Arrangement improves logical thinking, analytical ability, and problem-solving speed, making it one of the highest-scoring reasoning topics.
Linear Seating Arrangement questions are frequently asked in SSC (CGL, CHSL, CPO, MTS), Banking (IBPS, SBI, RBI), Railway (RRB), Insurance, ADRE, APSC, Assam Police, and other Central and State Government recruitment examinations. In this complete guide, you will learn the basic concepts, important rules, shortcut tricks, solved examples, and Linear Seating Arrangement MCQs with answers and detailed explanations to help you prepare effectively for your exams.
Types of Linear Seating Arrangement
There are two main types:
- Everyone Faces North
- Everyone Faces South
Understanding the facing direction is the most important part because left and right change when people face south.
Type 1: Everyone Faces North
When every person faces North, the left and right directions remain normal.
West ← → East
1 2 3 4 5 6 7
A B C D E F G
(All are facing North ↑)
Rules:
- Left = Actual Left
- Right = Actual Right
Example:
If A is sitting here, X A Y
- X is immediate left of A.
- Y is immediate right of A.
Type 2: Everyone Faces South
When everyone faces South, left and right become opposite.
West ← → East
1 2 3 4 5 6 7
A B C D E F G
(All are facing South ↓)
Rules:
- Person's Left = Actual Right
- Person's Right = Actual Left
Example
If A is sitting here, X A Y
Here,
- X is not on A's left Position.
Because A faces south, so,
- X becomes A's right.
- Y becomes A's left.
What if the Facing Direction (North/South) is Not Given?
If the question does not mention whether people are facing North or South, then follow these rules:
Rule 1: Assume Everyone Faces North (Default)
If the question simply says:
"Six persons A, B, C, D, E and F are sitting in a row."
and does not mention any facing direction, you should assume that everyone is facing North. So, you can say,
- A is to the left of B.
- Treat left and right as normal (actual left and actual right of you).
Rule 2: If People Face Each Other
If the question says:
"Five persons sit in one row facing five persons in another row."
then do not assume North. Instead, use the facing directions implied by the two rows:
- One row faces South.
- The opposite row faces North.
Left and right depend on the row each person belongs to.
Rule 3: If Different Directions Are Mentioned
Sometimes the question states:
- Some people face North.
- Some people face South.
In that case, apply the left/right rules separately for each person according to their own facing direction.
Summary Table
| Situation | Assumption |
| No facing direction mentioned | Assume everyone faces North |
| Everyone faces North | Left and right are normal as of you |
| Everyone faces South | Left and right are reversed |
| Two rows facing each other | Use the facing direction of each row |
| Mixed facing directions | Apply rules person-wise |
Some Basic Position Terms
1. Immediate Left
- Exactly one seat left.
- AB , here A is immediate left of B.
2. Immediate Right

- A X B , here B is second right of A.
5. Third Left
- Leave two persons.
- A X X B, here A is third left of B.
6. Third Right
- Leave two persons.
- A X X B, here B is third right of A.
7. Adjacent
- Immediate neighbour.
- AB, here A and B are adjacent.
8. Between
- A B C , here B is between A and C.
9. Extreme Left End
- A B C D E , here A sits at the extreme left( Assuming North facing).
10. Extreme Right End
- A B C D E , here E sits at the extreme right( Assuming North facing).
11. Middle Seat

Clue To Solve
Example 1
Suppose, six persons A, B, C, D, E and F sit in a row facing north. A sits at the extreme left. C sits second right of A. D sits immediate right of C. B sits at the extreme right. E sits left of D. How to arrange them.
Solution
Step 1
- Direction Identify
- Every one Facing North
Step 2
Identify Extreme left and right
A □ □ □ □ B
Step 3
C is second right of A.
A □ C □ □ B
Step 4
D is immediate right of C.
A □ C D □ B
Step 5
E sits left of D.
A E C D □ B
Step 6
Remaining person F.
A E C D F B
Example 2
Suppose, Five persons P, Q, R, S and T sit in a row facing south. P sits at one end. Q sits second left of P. R sits immediate right of Q. T sits at the other end. How to arrange them.
Solution
Step 1
- Direction Identify
- Since everyone faces south, left and right are reversed.
Here,
- Left = Actual Right
- Right = Actual Left
Step 2:
- Draw the Seats
- □ □ □ □ □
Step 2:
- Place P at One End
- Since the clue says "P sits at one end", there are two possibilities. Let's place P at any end first.
- P □ □ □ □
Step 3:
- Q Sits Second to the Left of P
- So, Move 2 seats to the actual right of P.
- P □ Q □ □
Step 4:
- R Sits Immediate Right of Q
- Again, everyone faces South, so Q's right is the actual left.
- Place R one seat to the actual left of Q.
- P R Q □ □
Step 5:
- T Sits at the Other End
- The remaining end is the right end.
- P R Q □ T
Step 6:
- Place the Remaining Person (S)
- Only one seat is left.
- P R Q S T
Common Mistakes
- Forgetting the facing direction.
- Treating south-facing arrangements like north-facing ones.
- Ignoring the word immediate.
- Confusing second left with immediate left.
- Not checking all clues after solving.
- Guessing positions without logical proof.

Q3. If Person A sits third to the right of Person B, and both are facing North, how many people are between them?
(A) 0
(B) 1
(C) 2
(D) 3
Explanation
Since both persons are facing North, "third to the right" means moving three seats to the right from B.
B □ □ A
So,there are 2 people (or 2 seats) between B and A.
So, Correct Answer (C) 2
Q4. If five people stand in a straight row facing North, which side is the immediate right of the person at the far left end?
(A) East
(B) West
(C) North
(D) South
Explanation
When everyone is facing North:
- Left = West
- Right = East
Suppose the five people are standing like this:
West ← → East
A B C D E
↑ ↑ ↑ ↑ ↑
(All are facing North)
- A is at the far left end.
- The person immediately to the right of A is B.
- Since the row extends towards the East, A's immediate right side is East.
So, Correct Answer: (A) East
Q5. Seven persons A, B, C, D, E, F, and G are sitting in a row. C sits in the middle. A sits second to the left of C. B sits immediate right of A. G sits at the extreme right. F sits immediate left of G. Who sits immediately right of C?
(A). D
(B). Either D or E
(C). F
(D). G
Explanation
Step 1
There is no direction , so assume all are seating in North Direction
Step 2
- Draw the seats
- □ □ □ □ □ □ □
Step 3
- C Sits in the Middle
- There are 7 seats, so the 4th seat is the middle.
- □ □ □ C □ □ □
Step 4
- A Sits Second to the Left of C
- Move 2 seats left from C.
- □ A □ C □ □ □
Step 5
- B Sits Immediate Right of A
- Place B one seat to the right of A.
□ A B C □ □ □
Step 6
- G Sits at the Extreme Right
- Place G in the last seat.
- □ A B C □ □ G
Step 7
- F Sits Immediate Left of G
- Place F one seat left of G.
- □ A B C □ F G
Step 8
- Place the Remaining person D or E
The remaining two empty seats are:
- Seat 1 or Seat 5
Therefore, there are two possible arrangements.
Possibility 1
- D A B C E F G
- Here, the person immediately right of C is E.
Possibility 2
- E A B C D F G
- Here, the person immediately right of C is D.
Since both arrangements satisfy all the given clues, the person immediately right of C is D or E.
