Campus Recruitment – Logical Reasoning – Seating Arrangement
Seating arrangement or complex arrangement is one of most important topic for Campus Recruitment tests.
In this type of questions, information about the seating arrangement of the persons or things is given in the form of a puzzle. You have to arrange the things in proper seating order by understanding the given logical statements and answer the question that follow. Problems on seating arrangement are mainly two types. They are
1) Linear arrangement
2) Circular arrangement
1) Linear arrangement: In this type, there exists left end and right end of the seating. This arrangement looks like a row or a line.
Here, right side of ’A’ are B, C, D, E, F and left side of ‘A’ is no one.
2) Circular Arrangement: In this type, it is not possible to say what is right end and left end (or) starting or ending points.
Tips to solve:
1) Read the given information and find an initial clue which is origin of the information.
2) If a statement does not give any clue to arrange, then note it down for further use. Use that information whenever it is required for proper arrangement.
3) Do not assume any condition on your own while solving the problem.
4) Be careful while choosing the correct clue to start.
5) If you sec the word like who or which then consider the second person in place of who/ which.
Example: Consider the statement, ‘G’ sits exactly opposite to B who is immediate right of ‘H’.
In this statement, the word who refers to B.
6) If you see the word and/ is/ but then consider first person in place of these words.
Example: Consider the statement, ‘A is opposite to B and is sitting on the left of C.
In this statement, the word and refers to A.
(I) 5 friends namely A, B, C, D, E are sitting in a row but not in the same order. D is not the neighbor of either A or E. E is not at the center. B sits at one end and third to the right of E (All are facing North).
1) Who sits exactly in the middle of the row?
a) E b) D c) B d) C e) none of these
2) Who sits at extreme ends?
a) CD b) EC c) DC d) EB e) AB
3) What is the position of B with reference to A?
a) 4th right b) 4lh left c) 3rd left d) 3rd right e) 2nd right
4) In which of the following pairs, first person sits immediate right of second person?
a) AE b) EC c) CD d) BD e) none of these
5) Who are the neighbors of C?
a) AE b) ED c) BD d) CD e) None
Explanation: In the given information, last point gives us a clue. i.e. B sits at one end and third to the right of E. B cannot be at left end because E should be left of B which is not possible. So, B sits at right end. D is not the neighbor of either A or E. So, D should sit at immediate left of B. C should sit at the center. Finally A sits at left end.
1) d; C sits in the middle of the row.
2) e; A and B sits at extreme ends.
3) a; The position of ‘B’ with reference to ‘A’ is 4th right.
4) d; In the given pairs only B sits immediate right of D.
5) b; The neighbor of ‘C are E and D.
(II) Six persons of family P, Q, R, S, T, U are sitting around a circular table to have dinner but not in the same order. P sits opposite to Q and immediate right of R. T is not the neighbor either P or U. Q sits second to the right of S and immediate left of U. S sits between T and P.
1) Who sits to the immediate left of Q?
a) T b) U c) R d) S e) P
2) Who are neighbors of U?
a) SP b) TS c) QR d) PR e) TR
3) In which of the following pair, second person sits immediate right of first person?
a) QU b) RU c) QT d) TS e) None of these
4) In which of the following pairs, first person sits between second and third person?
a) SPR b) TSQ c) QUR d) TSP e) RUQ
5) If we interchange the positions of S and U, T and R, P and Q then who who sits to the immediate right of P?
a) S b) Q c) U d) T e) R
xplanation: There is a clue in the first point itself, i.e. ‘P is opposite to Q and P is immediate right ofR’. Starting with this clue, we can arrange all the persons.
Observe the diagram below.
1) a; T sits immediate left of Q.
2) c; Q and R are the neighbors of U.
3) a; U sits immediate right of Q.
4) b; T sits between S and Q.
5) a; After interchanging the positions, will be immediate right of
