Reasoning Seating Arrangement shortcuts [How to Solve] Complete Explanation
Hi aspirants we have seen so many are struggling to solve Seating arrangement, actually it is one of the important, logical and easy topic in the on going SBI, IBPS, other banks PO, clerical and Competitive exams. Anyone can score if you just remember these tips we specified below.
There are various models in the seating arrangement like
- Single row arrangement
- Double row arrangement
- Circular arrangement
- Rectangular arrangement
1. Read the entire puzzle and understand the statements correctly
2. Identify the statements that give definite information.
For instance let us take three statements and evaluate them
Statement (a): A is to the left of B.
The data in the statement is basic but not definite as the statement ONLY says that A is to the left of B. but, it does not specify where A is located from B.
Statement (b): A is second to the left of B. The data in the statement is definite as it clearly states that A is placed second to the left of B.
Statement (c): T is between Q who plays football and P in order of seating in a row. It can be understood as ‘T is between Q and P. So, they may be seated as QTP or PTQ (so, the data is not definite) and ‘Q plays football’.
3. Search for the connecting information.
4. Figure out the seating arrangement by clearly identifying the directions
Persons sitting in a ROW all facing same direction:
Persons sitting in two ROWs facing each other:
Persons sitting in a CIRCLE or RECTANGLE or SQUARE facing the centre:
Seated to the left = Take clockwise direction
Seated to the right = Take Anti-clockwise direction
Persons sitting in two CIRCLE or RECTANGLE or SQUARE facing away from centre:
Seated to the left = Take Anti-clockwise direction
Seated to the right = Take clockwise direction
Now let us discuss this with an example:
A, B, C, D, E. F, G and H are sitting around a circle facing the centre.
a) E is to the immediate right o A, who is second to the right of G.
b) D is not an immediate neighbour of C or H.
c) F is third to the right of C and second to the left of H.
Now, let us discuss how to understand the statements correctly:
The statement (a) says: E is to the immediate right of A. A is second to the right of G.
The statement (c) says: F is third to the right of C. F is second to the left of H.
Normally, we will be tempted to solve the question by picking up point by point from first. But, that is not correct. We should be careful in selecting the points to solve the puzzle by searching for definite information. Here, though (a) and (c) are definite points, we have to pick up (c) first as this point is connected to the point (b) (as ‘C’ and ‘H’ are discussed in both the points). In case, we take point (a) it is difficult to solve the question.
In circular sitting arrangement, you have to arrange people or objects around a circle, as per the given information in the questions.
In normal circular arrangement, persons are sitting around a circle and facing the centre.
a. Left movement is called clock- wise rotation.
b. Right movement is called anti – clock- wise rotation.
According to the information, you have to specify the position of all the persons in the arrangement. The positions are specified through conditions like a particular person is sitting right or left of another person.
Question – Four persons are A, B, C and D is sitting in a circle facing the centre. A is sitting second to the left of D. C is sitting third to the right of A. C is sitting opposite to B.
(i) First step is to read the information and draw a circle.
(ii) After drawing a circle, find out who is on right side and who is on left side of.
(iii) Pick one information first and solve the questions accordingly. In question, it is given A is sitting second to the left of D. So, you have to fix the place of A and D in a circle.
After fixing the place of A and D, we will move to another information. Now, here it is given, C is sitting third to the right of A.
After fixing the place of A, D and C, we will move to another information. C is sitting opposite to B.
7 golden rules of circular arrangements in
(i) Draw a circle – mark the places (4/6/7/8) – and then start reading the question!
(ii) Arrange the information in every sentence – if possible – if not – write it down beside you circle in shorthand – to be arranged when further information clarifies the position.
(iii) If you find a situation where, supposing, A can be seated in 2 different places – then, go ahead with one place and arrange the rest accordingly – if you successfully arrange the entire thing – then the A’s place which you had arbitrarily decided is the correct place!
If it is not correct you’ll find that your arrangement of A’s position is contradicting as per other information in the question and you can then chose the other A’s possible position.
Okay, another one – if P has two possible ways to be seated – namely Seat 1 and Seat 2. You are not understanding from the available information, where to seat P. So you, arbitrarily seat him in either Seat 1 or Seat 2.
Let’s say you seated him at Seat 2 – ok – now go ahead and try seating the others as per the rest of the information in the question.
If you are able to seat ‘em all without any contradictions or problems, you have successfully solved the question and P’s seat that you chose is correct.
And if you find a contradiction of P’s Seat 2 – then you immediately know for sure that Seat 2 is not the right place of P and it has to be Seat 1, as there were only 2 possibilities!
(iv) Always arrange those person’s around your circle, whose positions are 100% clear and accurate. Keep the persons who you have a doubt on a little farther away so you know who’s definitely sitting correct and who you need to revise the seating for!
Or, put a tick on the persons who are seated correct.
This brings clarity to the fact that – these people are sitting right and these places are not available for further arrangement – the rest need to be arranged in the available places only.
(v) If there are 4/6/8/10 persons, i.e., even number of people and all facing one particular direction – then 2nd/ 3rd / 4th / 5th to the left or right is always the person sitting opposite!
(vi) Where some are facing outward and some facing inward, then mark the places with arrows pointing inward/outward.
Like in this figure, A and D are facing outward and so their arrows are pointing away from the centre; while, B and C are facing inward with their arrows pointing towards the circle.
I usually more my rough sheet around without wasting my time and get the positions correct!
(vii) Practice! The Golden Rule to solving Seating Arrangements – advocated everywhere by everyone is – LOTS OF PRACTICE!
Honestly, there is no other way around it!
Question: Eight friends P, Q, R, S, T, U, V and W are sitting in a circle facing the centre. Q is sitting between V and S. W is third to the left of Q and second to the right of P. R is sitting between P and V. Q and T are not sitting opposite to each other.
1. Who is third to the left of S?
D. Cannot be determined
E. None of these
Solutions: First step is to draw a circular figure having eight persons. Now, fix the place of the persons or friends one by one according to the information.
Q is sitting between V and S. Here position of V and S is exactly not confirm, so we will skip this information and move to another information, which will fix the place of the person is a circle in a specific place.
Next information is – W is third to the left of Q and second to the right of P.
Here, it is important to note that – W is third to the left of Q and also second to the right of P. Some student’s confuse in this information and pick information as Q is second to the right of P, which is wrong.
After the fixing the place of W, P and Q we will move to another information. R is sitting between P and V. Q is sitting between V and S.
After the fixing the place of W, P, Q, V, R and S; we will move to another information. Q and T are not sitting opposite to each other means opposite of Q is U and T is sitting between S and W.
Now the correct answers is
1. (1) Third to the left of S is U.
Tips to solve ‘Seating Arrangement” questions
1. First step is to take a quick glance on the given information and you will get an idea of the situation of the persons.
2. Second step is to pick the useful information which is “definite information” and fix the place accordingly. For e.g. – A is sitting second to the left of B.
3. Do not pick the negative information in first step. Negative information means – which information does not tell anything definitely but it gives an idea to eliminate a possibility. For e.g. – A is not sitting on the immediate left of B. or B is not opposite of E.
Important note: Meaning of – and, who and adjacent in seating arrangement.
1. 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.
2. 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.
3. 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.
