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.

1) 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
Dis 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 (e) C and E

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 (d).
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).


2)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).


3)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).
