Seating Arrangement: Best Aptitude Questions With Tips and Tricks

0 min read

Seating arrangement plays a crucial role in reasoning tests, where candidates are often presented with conditions or rules that dictate how individuals or items should be arranged in a particular order.

By studying the information and correctly applying logic, you can determine the right seating order that meets all the rules. Practising different seating problems can boost test scores and thinking skills.

Key Concepts in Seating Arrangement

Let us understand the key concepts for seating arrangement in reasoning:

Logical Reasoning Skills

Mastering logical reasoning through practice and utilizing reasoning resources can enhance one's ability to tackle seating arrangement questions efficiently. This skill is essential for various competitive exams, job interviews, and daily problem-solving scenarios.

Essential Concepts & Principles

To excel in seating arrangement reasoning, grasping fundamental concepts such as direction sense, order ranking, blood relations, etc., is vital. Applying principles like creating diagrams or grids while solving puzzles enhances clarity and organization when arranging persons based on conditions.

Types of Seating Arrangement Questions

To begin with, let us understand the different types of seating arrangement questions:

Linear seating arrangements

Linear seating arrangements involve arranging individuals in a straight line. Properties of linear seating include facing each other or facing the same direction. Linear setups can be tricky when choosing who sits at the ends or next to specific individuals.

Example

In a logical and aptitude test, a suitable example of a linear seating arrangement could be as follows:

A, B, C, D, and E - are friends sitting in a row looking towards the north. They like different colors - red, blue, green, yellow, and orange. The following information is known:

A is sitting at one of the ends.
B is sitting next to E and does not like red.
C is sitting at the extreme left end and likes green.
D is sitting between A and C.
The person who likes blue is sitting next to the person who likes yellow.

Linear Seating Arrangements characteristics:

Easy visualization

Clear ordering of seats

Simple directions for positioning

Circular seating arrangements

Circular seating involves placing people around a table or in a circular formation. The arrangement revolves around fixed points like centre-facing chairs or fixed positions on the circle's circumference.

Understanding properties such as clockwise or counterclockwise direction is key. In circular setups, identifying immediate neighbours can be challenging due to continuous rotation possibilities.

Example

For a logical test involving circular seating arrangements, consider a scenario where six friends - A, B, C, D, E, and F - are seated around a circular table facing the centre. The following conditions apply:

A is sitting two seats away from B.
C is seated next to D.
E is not sitting next to F.

Circular seating characteristics:

Equidistant placement from the center

Directional considerations

Fixed central point reference

Polygonal seating arrangements

Polygonal arrangements are complex configurations where individuals are seated along multiple sides, forming shapes like squares, rectangles, or hexagons. These setups require attention to angles and distances between each person based on their position within the shape.

Example

In a logical and aptitude test, a suitable example of polygonal seating arrangements could be as follows:

Six friends - Alex, Ben, Chris, David, Emily, and Fiona - are seated around a hexagonal table. The following conditions apply:

Alex is seated opposite to Ben.
Chris is seated next to Fiona.
David is not seated next to Emily.

Polygonal seating characteristics:

Different angle considerations

Varying distance calculations

Unique corner interactions

Navigating polygonal arrangements demands understanding geometric relationships among participants positioned across different edges.

Concentric Seating Arrangement

Concentric seating arrangement

Concentric seating arrangements place individuals in a circular formation, with each subsequent circle surrounding the centre. This setup creates a dynamic where participants are positioned based on their relation to the core point.

In this configuration, those closer to the middle have varying degrees of influence or importance compared to those on the outer edges.

Example

Consider a situation with three concentric circles labelled A, B, and C in a concentric seating arrangement scenario. Each circle represents a different group of people. Circle A contains 10 people, Circle B comprises 15 people, and Circle C includes 20. How many handshakes will occur if each person shakes hands with everyone in the other two circles?

Tips on How to Solve Seating Arrangement Questions

Let us look at some of the important rules to be followed while solving seating arrangement questions:

Understand the Question

Seating arrangement questions involve arranging people or objects around a table. These questions may include conditions like "A is sitting next to B" or "C is opposite D." To solve them, carefully read and visualize the given information. Key clues can be phrases like "next to," "opposite of," or "between."

Use Elimination Techniques

Eliminate impossible options based on given conditions. For instance, if P must sit beside Q and R cannot sit next to S, use this information to eliminate choices where P is not near Q or R is beside S. This method helps narrow down possibilities quickly.

Keep Track of Information

Maintain a clear record of all details provided in the question while solving seating arrangement problems. This prevents confusion and ensures no conditions are overlooked during analysis.

Common Mistakes to Avoid in Seating Arrangement Problems

Let us study some of the common mistakes that you need to avoid while solving seating arrangement questions:

Overlooking Important Details

When tackling seating arrangement problems, a common mistake is overlooking vital details. Missing key information can lead to incorrect conclusions. Another aspect often overlooked is the total number of people involved.

Not accounting for the exact number of individuals in the arrangement may cause confusion and errors when arranging the seats.

Falling into Traps

Individuals attempting seating arrangement questions might fall into traps set within the problem statement. These traps are designed to mislead and confuse, leading to incorrect solutions if not identified promptly.

Making Careless Mistakes

Carelessness during the solving process can also lead to errors in seating arrangements. Failing to double-check placements or missing out on subtle clues provided in the question can result in wrong answers.

10 Sample Practice Questions with Answers

Let us study some of the sample questions of seating arrangement with solutions of seating arrangement:

Question 1: In a linear seating arrangement, there are seven people sitting in a row facing north. A sits third to the right of B. C is sitting at one of the ends. D is not an immediate neighbor of C. E is sitting second to the left of F. G is sitting at one of the ends. Who is sitting in the middle?

Solution

Let's start by placing C at one end of the row.

Since D is not C's immediate neighbor, D cannot sit at either end.

From the given information, we know that A sits third to the right of B, so we can place B and A accordingly.

Since E is sitting second to the left of F, we can place them in relation to each other.

Finally, we can place G at the remaining end of the row.

Based on the positions of all the other people, we can determine that F is sitting in the middle of the row.

Question 2: How can you arrange 8 people around a circular table so that no two related individuals sit next to each other?

Solution

To ensure that no two related individuals sit next to each other around a circular table, you can follow these steps:

Assign each person a number from 1 to 8.

Seat the individuals with odd-numbered relationships (1, 3, 5, 7) at the even-numbered seats around the table (2, 4, 6, 8).

Seat the individuals with even-numbered relationships (2, 4, 6, 8) at the odd-numbered seats around the table (1, 3, 5, 7).

By following this arrangement, you can ensure that no two related individuals are seated next to each other.

Question 3: 5 friends - A, B, C, D, and E are sitting around a circular table facing the centre. A is sitting to the immediate left of B, D is sitting opposite to E, and C is sitting to the immediate right of E. Who is sitting between A and D?

Solution

Let's assume that A is sitting at position 1, B at position 2, C at position 3, D at position 4, and E at position 5. Since A is sitting to the immediate left of B, we can place them accordingly.

Now, D is sitting opposite to E, so they will be placed opposite to each other. C is sitting to the immediate right of E, so C will be placed next to E.

The seating arrangement is as follows: A - B - C - E - D

Therefore, D is sitting between A and C.

Question 4: Five friends, P, Q, R, S, and T, sit around a circular table facing the centre. P is sitting second to the right of Q. R is sitting second to the left of S. T is seated opposite to R. Who is sitting between P and T?

Solution

First, we need to determine the positions of each friend around the table:

P is second to the right of Q.

R is second to the left of S.

T is sitting opposite R.

Now, let's start by assuming the positions of Q and P:

Let's place Q at the top of the table.

P is second to the right of Q, so P is sitting two seats clockwise from Q.

Let's place R and S based on the given information:

R is sitting second to the left of S, so R is two seats anticlockwise from S.

Since T is sitting opposite R, T must be exactly opposite R on the table.

Now, we have Q at the top, with P two seats clockwise, R two seats anticlockwise, S next to R, and T opposite R.

Therefore, the seating arrangement is Q, P, S, R, T. From the arrangement, we can see that S sits between P and T on the circular table.

Question 5: In a concentric seating arrangement, there are three circles with radii of 3 meters, 5 meters, and 7 meters. If a person is seated at the centre of the smallest circle, how many people can be seated in total if each circle can accommodate 4 people per meter of its radius?

Solution

The smallest circle with a radius of 3 meters can accommodate 12 people (3 meters x 4 people/meter).

The middle circle with a radius of 5 meters can accommodate 20 people (5 meters x 4 people/meter).

The largest circle with a radius of 7 meters can accommodate 28 people (7 meters x 4 people/meter).

Therefore, the total number of people that can be seated in the concentric arrangement is 12 + 20 + 28 = 60 people.

Question 6: In a concentric seating arrangement, there are 5 people seated in the innermost circle, 10 people in the middle circle, and 15 people in the outermost circle. If each person shakes hands with every other person once, how many handshakes took place in total?

Solution

To find the total number of handshakes, we need to calculate the number of handshakes within each circle and then add them together.

For the innermost circle with 5 people, the number of handshakes can be calculated using the formula n(n-1)/2, where n represents the number of people.

So, for 5 people, the number of handshakes is 5(5-1)/2 = 10 handshakes.

For the middle circle with 10 people, the number of handshakes is 10(10-1)/2 = 45 handshakes.

And for the outermost circle with 15 people, the number of handshakes is 15(15-1)/2 = 105 handshakes.

Adding these together, we get a total of 10 + 45 + 105 = 160 handshakes that took place in total.

Question 7: A, B, C, D, E, F, G, and H are 8 friends seated in a circular arrangement facing the centre. A is sitting third to the left of B. G is sitting second to the right of A. F is sitting second to the right of H. D is sitting second to the left of E. Who is sitting between C and D?

Solution

Start by placing A in the seating arrangement, as it is given that A is third to the left of B. So, let's place A and B in the arrangement: B - - A

Next, place G as it is given that G is second to the right of A: B - G A

Now, place F as it is given that F is second to the right of H: B - G A F

Place H to determine the position of F: B H G A F

Now, place D as it is given that D is second to the left of E: B H G D A F

Place E to complete the arrangement: B H G D E A F

Finally, place C in the remaining spot between C and D: B H G D E A C F

So, C is sitting between C and D in the circular seating arrangement.

Question 8: In a linear seating arrangement, A, B, C, D, E, F, G, and H are 8 friends sitting in a row facing north. They have different professions - Lawyer, Doctor, Engineer, Teacher, Artist, Chef, Pilot, and Scientist. The following information is known:

A, who is a Lawyer, is sitting at one of the extreme ends.
The Chef is sitting third to the right of A.
E, who is a Doctor, is sitting at one of the extreme ends.
B is sitting between E and F. B is not an Engineer.
G is a Pilot and is sitting next to F.
H is an artist sitting next to the engineer.
The Scientist is sitting at the centre of the row.

Based on the given information, determine the profession of each friend and their seating positions from left to right.

Solution

From points 1 and 3, we know that A (Lawyer) and E (Doctor) are at the extreme ends.

From point 2, Chef is third to the right of A. So, A must be at the left end, and Chef must be at the 4th position.

From point 4, B is sitting between E and F. So, B must be a Teacher.

From point 5, G (Pilot) is next to F. So, F must be an Engineer.

From point 6, H (Artist) is next to the Engineer (F).

From point 7, the Scientist must be at the center. So, C must be a Scientist.

Therefore, the seating arrangement and professions from left to right are: A (Lawyer), B (Teacher), E (Doctor), G (Pilot), F (Engineer), H (Artist), C (Scientist), D (Chef).

Question 9: In a concentric seating arrangement, there are 5 rings with 6 seats in each ring. If each seat is numbered from 1 to 30, starting from the outermost ring and moving towards the centre, how many seats are there between seat number 12 and seat number 17?

Solution

To find the number of seats between seat number 12 and seat number 17, we need to calculate the total number of seats up to seat number 17 and then subtract the total number of seats up to seat number 12.

Seat number 17 is in the second ring, so there are 6 seats in the outermost ring and 6 seats in the second ring before seat number 17. This gives us a total of 12 seats up to seat number 17.

Seat number 12 is in the first ring, so there are only 6 seats in the outermost ring before seat number 12.

Therefore, the number of seats between seat number 12 and seat number 17 is 12 - 6 = 6 seats.

Question 10: A, B, C, D, and E are friends who are standing in a row looking towards the north.

A is sitting at one of the ends.
B is sitting to the right of C.
D is sitting between B and E.
C is not sitting at any of the ends.

Based on the given information, determine the seating arrangement of the five friends.

Solution

From point 1, we know that A is sitting at one of the ends. Therefore, A can only be at the left end or the right end. Let's consider both possibilities:

Case 1: A is at the left end

A _ _ _ _

From point 2, B is sitting to the right of C. Since C cannot be at either end, C must be in the middle. Therefore, the arrangement becomes:

A C B _ _

From point 3, D is sitting between B and E. Since E is not mentioned in any other condition, we can place E at the right end:

A C B D E

Therefore, the final seating arrangement is A, C, B, D, E.

Case 2: A is at the right end _ _ _ _ A

Using the same logic as above, we can determine that the final seating arrangement in this case is: C B D E A

Therefore, there are two possible seating arrangements:

A C B D E

C B D E A
