PROBLEMS ON SEATING ARRANGEMENT
SEATING
ARRANGEMENTS
In this type of questions,
some clues regarding seating or placing (linear/ circular)of some persons or
items is given. The candidate is required to form the paper sequence using
these clues and answer the questions accordingly.
I) Read the following
information carefully and answer the
questions given below:
Six persons A,B,C,D,E
and F are sitting in two rows, three in each. E is not at the end of any row D is
second to the left of F. C the neighbour of E, is sitting diagonally opposite
to D. B is the neighbour of F.
1. Which of the following are sitting diagonally
opposite
to each other?
(a) F and C (b) D and A (c) A and C (d)
A and F
(e) A and B
2. Who is facing B?
(a) A (b) C (c) D (d) E (e) F
3. Which of
the following are in same row?
(a)A and E (b) E and D (c) C and B (d) A and B
4. Which of the
following are in one of the two rows?
(a) FBC (b) CEB (c) DBF (d) AEF (e) ABF
5. After interchanging
seat with E, who will be the
neighbours
of D in the new position?
(a) C and A (b) F and B (c) only B (d) only A (e) only C
Solution:
The given
information can be analysed as follows:
E is not at end so; E must be in the middle of one of the
rows.
D is second to the left of F so, order of rows must be
D_F.
C is neighbour of E and is sitting diagonally opposite to
D means C is under F in the other row i.e. D _ F _ E C.
B is neighbour of F; s the arrangement must be D B F A E
C.
1. Other than D and C, A and F are sitting diagonally
opposite to each other,
as seen in the arrangement. So
the answer is(d).
2. Clearly, E is opposite to B in the other row. So, E is
facing B and the
answer is (d).
3. Clearly, from amongst the given alternatives, A and E
are in the same row
.So the answer is (a).
4. Clearly, from amongst the given alternatives, D,B and F
are in the same row.
So, the answer is (c).
5. Clearly, neighbours of E are A and C. So, on
interchanging the
seat with E, the new neighbours of D
will be A and C.
So the answer is (a).
II) Eight
books are kept one over the other counting from
the top the second, fifth and sixth books
are on plays.
Two books on plays are between two books on
composition.
One book of plays is between two books on poetry.
While
the book at the top of the book of
literature is a book
of composition.
Which book is fourth from the top?
(a) plays (b) poetry (c) composition (d)literature
Solution:
We analyse
the given information as follows :
Let C denote 'composition' , P denote 'plays' , Po denote 'poetry' and L denote 'literature'.
1 2 3 4 5 6 7 8
_ P _ _ P P _ _
_ _ _ C P P C _
Po P Po _ _ _ _ _
_ _ _ _ _ _ C L
So the
arrangement becomes:
1 2 3 4 5 6 7 8
Po P Po C P P C L
Clearly
the fourth book from the top is on composition. So the answer is (c).
III) Read
the following information and answer the
Questions that follows.
(1)Six
friends A, B, C, D, E and F are sitting in a closed
circle facing the center.
(2)E is to
the left of D.
(3)C is
between A and B.
(4)F is
between E and A.
1. Who is
to the left of B?
(a) A (b) C (c) D (d)
E (e) none of these
2. Who is
to the right of C?
(a) A (b) B (c) D (d)
E (e)F
3. Which
of the above given statements is superfluous?
(a) 1 (b) 2 (c) 3 (d)
4 (e) none of these
Solution:
Clearly, in the circle this arrangement is as shown
D
B E
C F
A
1. Clearly, D is the left of B. So the answer is (C)
2. Clearly, A is to the right of C. so the answer is (a).
3. Since all the statements are necessary to determine the
arrangement none
of them is superfluous. So the answer
is (e).
EXERCISE
1. Four girls are sitting on a bench to
be photographed.
Shikha is to the left of Reena. Manju is to
the right
of Reena. Rita is between Reena and Manju.
Who
would be second from the left in the photograph?
(a) Reena (b) Shikha (c) Manju (d) Rita
Answer
is (d)
Shikha is to the left of Reena and Manju is to her right.
Rita is between Reena and Manju. So the order is Shikha
,Reena , Rita and Manju. In the photograph Rita will be second from left.
2. There are five different houses, A to
E in a row. A is
to the right of B and E is to the left of C
and right
of A. B is to the right of D.
Which
of the houses is in the middle?
(a) A (b)
B (c) D (d) E
Answer is
(a)
B is to the right of D. A is to the right of B. E is to the
right of A and left of C. So the order is in the middle.
D, B, A, E, C. Clearly A is in the middle.

3.
In
a march past, seven persons are standing in a row. Q is standing left to R but
right to P. O is standing right to N and left to P.Similarly, S is standing
right to R and left to T.
Find out who is standing in middle?
(a) P (b)
Q (c) R (d) O
Answer
is (b)
Q is left to R and to the right of P i.e. P, Q, R.
O is to the right of N and left of P i.e. N, O, P.
S is to the right of R and left of T i.e. R, S, T.

4. Five
children are sitting in a row. S is sitting next to
P but not T. K is sitting next to R who is
sitting on
extreme left and T is not sitting next to K.
Who are
sitting adjacent to S?
(a) K and P (b) R and P (c) only C d) P
and T (e)Insufficient
Answer
is (d)
S is sitting next to P. So, the order S, P or P, S is
followed. K is sitting next to R. So, the order R, K is followed because R is
on the extreme left. T is not next to P or K. So, the arrangement will be R, K,
P, S, T.
Clearly, P and T are sitting adjacent to S.

(4)Miss D sits opposite to Mr C.
What are
the trades of A and B?
(a) Tailor and Barber (c)
Barber and Cook
(b) Tailor and Cook (d)
Washer man and Cook.
Solution: (b)
C and D sit opposite to each other .So if A sits opposite
to cook, B shall be cook.
Now B is to the right of barber. So, one of the rest say C
will be barber, then D. On the opposite side shall be washer man or tailor.
But washer man is on the left of tailor and A is to the left of D. So, A is
washer man and D is tailor. Thus, A and B are Washer man and Cook.

11. Six
friends A, B, C, D, E and F are sitting in a closed
Circle facing the center.
A is facing D. C is between A and B. F is between E and A.
Who is to the immediate left of B?
(a) A (b) C (c) D (d) E
Answer is
(b)
Clearly, in a circle the arrangement is as shown:
A
C F
B E
D
So, C is to the immediate left of B hence the answer is
(b)
According to my opinion there can be another arrangement
based on the given details:
A
F C
E B
D
Hence D is the immediate left of B… so the answer could be
(c ) as well….
12. A, B,

The circular arrangement is as shown
C
A E
F B
D
Answer:
1.
(a), Clearly B is facing A.
2.

H is third to the left of B and second to the right of A.
So, forming a circle we have:
H A
G D
B
C is between A and G. But E is not opposite B. So, C is
between A and H.
C
H
A
F
E
G D
