Seating Arrangement Reasoning Questions
Seating arrangement questions describe where people sit, in a row, around a circle or in two rows, and ask about their positions. Draw the layout first, fix each person’s facing direction, place the definite clues before the relative ones, and test every remaining case. Left and right depend on which way each person faces.
Seating arrangements are one of the standard puzzle types in reasoning sections. Our guides to Infosys and Cognizant both list them among the commonly reported topics, and they sit alongside blood relations, syllogisms and coding-decoding.
What Are Seating Arrangement Questions?
You get a set of clues about a group of people (“B sits second to the left of A”, “C sits opposite D”) and must work out the full arrangement, then answer questions about it. There are three common layouts:
- Linear: everyone sits in one row, usually all facing the same way, sometimes facing different ways.
- Circular: everyone sits around a table, facing the centre, facing outward, or a mix of both.
- Double row: two rows face each other, so each person sits opposite someone in the other row.
Nothing outside the clues is needed. The skill is turning each clue into a position and not mixing up left and right.
Left and Right Depend on Facing
This is where most mistakes happen. A person’s left and right are decided by the direction they face, not by the page.
| Layout | The person faces | Their left is | Their right is |
|---|---|---|---|
| Row, seen from above | North | West (left side of the page) | East (right side of the page) |
| Row, seen from above | South | East (right side of the page) | West (left side of the page) |
| Circle | The centre | The next person clockwise | The next person anticlockwise |
| Circle | Outward | The next person anticlockwise | The next person clockwise |
So when two people in a row face opposite ways, their “left” points in opposite directions. In a circle, switching from facing the centre to facing outward swaps every left and right.
Useful Terms
| Phrase | Meaning |
|---|---|
| Immediate left or right | The person directly next to them on that side |
| Second to the left or right | One person sits in between |
| Between A and B | Somewhere in the gap between them, often directly in the middle |
| Opposite (circle) | Directly across the table, half the circle away. This needs an even number of people |
| Extreme end | The first or last seat in a row |
| Neighbour | Either person directly beside them |
A Step-by-Step Method
- Draw the layout with the right number of seats, and mark the direction each person faces.
- Place the definite clues first, such as “A sits at the extreme left”, which fix a person in one position.
- Combine the relative clues (“B is immediately right of C”) into small blocks, and place those blocks next.
- Use the negative clues (“D is not next to E”) to rule out options.
- When more than one case remains, branch. Try each case against every clue and drop the ones that break a clue.
- Answer only what is true in every remaining case.
- In a circle, fix one person first. Rotating the whole table doesn’t change the arrangement, so one person’s seat is free to choose, and everyone else is placed relative to them.
Solved Examples
1. Linear row. Five people P, Q, R, S and T sit in a row facing north. R sits at the extreme right. Q sits second to the left of R. P sits immediately to the left of S. Who sits in the middle? Answer: Q. Number the seats 1 to 5 from the left. R is in seat 5, and second to the left of R is seat 3, so Q is in seat 3. P sits immediately left of S, which needs two adjacent seats from 1, 2 and 4, and the only pair is seats 1 and 2, so P is in 1 and S in 2. That leaves T in seat 4. The row is P, S, Q, T, R.
2. Different facing directions. X, Y and Z sit in a row, and seen from above they are X, Y, Z from the left side of the page to the right. X and Z face north, and Y faces south. Who sits to the immediate left of Y? Answer: Z. Y faces south, so Y’s left is east, the right side of the page. The person on that side is Z. (Y’s right is X.)
3. Circle facing the centre. Six people A, B, C, D, E and F sit around a circular table facing the centre. A sits opposite D. B sits to the immediate right of A. F sits to the immediate left of D. E sits second to the left of B. Who sits between C and F, and who sits opposite B? Answer: D sits between C and F, and C sits opposite B. Number the seats 1 to 6 clockwise and put A in seat 1. D is opposite, so D is in seat 4. Facing the centre, a person’s right is the anticlockwise neighbour, so B is in seat 6. Left is clockwise, so F, immediately left of D, is in seat 5. E is second to the left of B, which is two seats clockwise from seat 6, so E is in seat 2. C takes the last seat, 3. Clockwise the order is A, E, C, D, F, B. D sits between C and F, and the person opposite B (seat 6) is in seat 3, which is C.
4. The same circle, facing outward. In the arrangement from example 3, suppose everyone faces outward instead. Who sits to the immediate right of E? Answer: C. E is in seat 2. Facing outward, right is clockwise, so E’s immediate right is seat 3, which is C. When everyone faced the centre, E’s immediate right was A. Switching direction swapped the answer.
5. Double row. Six people sit in two rows of three, each person facing someone in the other row. A, B and C sit in row 1, facing north. P, Q and R sit in row 2, facing south. A sits at the extreme left end of row 1. P sits opposite A. Q sits at the extreme left end of row 2. C sits opposite Q. Who sits at the extreme right end of row 2, and who is to the immediate left of R? Answer: P sits at the extreme right end of row 2, and Q is to the immediate left of R. Number the seat positions 1 to 3 from the left side of the page, in both rows. A faces north, so the extreme left end is position 1. P sits opposite A, so P is in position 1 of row 2. Row 2 faces south, so its left is east, and the extreme left end is position 3, which makes Q’s seat position 3. R is then in position 2. C sits opposite Q, so C is in position 3 of row 1, and B in position 2. For row 2 the right end is the west end, position 1, which is P. R faces south, so R’s left is east, position 3, which is Q.
Common Mistakes
- Ignoring facing direction. Before you place anyone, note which way they face. A “left” for a south-facing person is the opposite side of the page.
- Counting “second to the left” as next to them. Second means one person sits in between.
- Forcing “opposite” onto an odd circle. Opposite only works when the number of seats is even.
- Fixing too many people in a circle. Only the first person’s seat is free to choose. Every other seat comes from the clues.
- Answering from one case when several remain. If the clues allow more than one arrangement, only an answer true in all of them is safe.
Practice Questions
Try each on paper, then check the answer.
1. Four friends A, B, C and D sit in a row facing north. B sits at the extreme left. C sits immediately to the right of B. D sits at the extreme right. Who sits between C and D? Answer: A. The row is B, C, A, D, so A is the only person left for seat 3.
2. Five people P, Q, R, S and T sit in a row facing north. S sits at the extreme left. T sits second to the right of S. Q sits immediately to the left of R. Who sits between S and T, and who sits at the extreme right? Answer: P sits between S and T, and R sits at the extreme right. S is in seat 1, and T is two seats to the right, in seat 3. The remaining seats are 2, 4 and 5. Q immediately left of R needs two adjacent seats, and the only pair is 4 and 5, so Q is in 4 and R in 5. P takes seat 2.
3. X, Y and Z sit in a row, and seen from above they are X, Y, Z from the left of the page to the right. X faces north, Y faces south and Z faces north. Who sits to the immediate right of Y? Answer: X. Y faces south, so Y’s right is west, the left side of the page, where X sits.
4. Six people A, B, C, D, E and F sit around a circular table facing the centre. D sits opposite A. B sits to the immediate left of A. F sits to the immediate left of D. E sits to the immediate right of A. Who sits between B and D, and who sits opposite B? Answer: C sits between B and D, and F sits opposite B. Put A in seat 1, clockwise. D is in seat 4. Facing the centre, left is clockwise, so B is in seat 2. F, immediately left of D, is in seat 5. Right is anticlockwise, so E, immediately right of A, is in seat 6. C takes seat 3. C is between B and D. Opposite B (seat 2) is seat 5, which is F.
5. In the arrangement from question 4, suppose everyone faced outward. Who would sit to the immediate right of A? Answer: B. A is in seat 1. Facing outward, right is clockwise, so A’s immediate right is seat 2, which is B. (Facing the centre it was E.)
6. Six people sit in two rows of three. Row 1 has P, Q and R facing south. Row 2 has X, Y and Z facing north. Each person faces someone in the other row. P sits at the extreme left end of row 1. X sits opposite P. Z sits at the extreme left end of row 2. Q sits opposite Z. Who sits opposite Y, and who sits at the extreme right end of row 1? Answer: R sits opposite Y, and Q sits at the extreme right end of row 1. Number the positions 1 to 3 from the left of the page. Row 1 faces south, so its left is east, and P at the extreme left end is in position 3. X sits opposite P, so X is in position 3 of row 2. Row 2 faces north, so its left is west, and Z at the extreme left end is in position 1. Y is then in position 2. Q sits opposite Z, so Q is in position 1 of row 1, and R in position 2. R is opposite Y. For row 1 the right end is the west end, position 1, which is Q.
7. Eight people A, B, C, D, E, F, G and H sit around a circular table facing the centre, in the order A, B, C, D, E, F, G, H going clockwise. Who sits opposite C, and who sits second to the left of F? Answer: G sits opposite C, and H sits second to the left of F. C is the third person, and opposite is four seats away, which is the seventh person, G. Facing the centre, left is clockwise. Counting two seats clockwise from F gives G, then H.
8. Five people A, B, C, D and E sit in a row facing north. B sits somewhere to the right of A, and C sits somewhere to the right of B. Which of the five could sit at the extreme left? Answer: A, D or E. A must be left of B, and B left of C, so B and C can’t be at the extreme left. A, D or E could be, because nothing in the clues rules them out. This is why puzzles that give only relative clues leave several cases open.
Frequently Asked Questions
What are seating arrangement questions in reasoning?
They describe how a group of people sit, in a row, around a table or in two rows, using clues about positions. You place everyone and then answer questions about the arrangement.
How do I solve circular seating arrangement questions?
Number the seats clockwise and fix one person’s seat. Remember that facing the centre, a person’s left is the next person clockwise, and facing outward it is anticlockwise. Then place the others one clue at a time.
How do left and right work when people face different directions?
A person’s left and right depend on the direction they face. For a person facing south in a row seen from above, left is east, which is the right side of the page.
What does “opposite” mean in a circular arrangement?
It means directly across the table, half the circle away. This only works when the number of people is even.
Why do some seating puzzles leave more than one possible arrangement?
When the clues are only relative, several arrangements can fit. Try each case against every clue, and only trust an answer that is true in all remaining cases.
Which exams ask seating arrangement questions?
They appear in the reasoning sections of placement tests and in many bank and SSC exams. Our Infosys and Cognizant guides list them among the commonly reported topics.
