Linear Arrangement - Opposite Direction
In a linear arrangement, things or persons are arranged linearly in rows or columns. In a linear arrangement, the right or left of a person depends on which direction the person is facing.
Illustration: Eight persons A, B, C, D, E, F, G, and H are sitting in a straight line at equal distances, but not necessarily in the same order. Four of them are facing north and four of them are facing south.
D who is facing south is sitting fourth to the left of H, who is sitting between two persons facing opposite directions to each other. Immediate neighbours of B face the same direction. Neither D nor H sits at the extreme ends. G is sitting third to the left of C and is sitting at one of the extreme ends. A and D are immediate neighbours and face opposite directions to each other. E is sitting to the immediate right of G, who is fifth to the left of F. D and G face the same direction.
Who is sitting exactly between the B and E?
A. C,D B. C,H C. G,C D. A,F E. None of these
Answer: B
Solution: According to the first statement it is given that D who is facing south is sitting fourth to the left of H. and also D does not sit at the extreme ends. The two possibilities are shown in the figure I and figure II.
|
Figure I |
Figure II |
In the statement it is given A and D are immediate neighbours and face opposite directions to each other. So according to the figure I the two possibilities are shown in Figure III and Figure IV
|
Figure III |
Figure IV |
and according to Figure II the two possibilities are shown in Figure V and Figure VI
|
Figure V |
Figure VI |
In the statement it is given G is sitting third to the left of C and is sitting at one of the extreme ends. So according to the figure III the possibility is shown in Figure VII and according to the figure IV the possibility is shown in Figure VIII
|
Figure VII |
Figure VIII |
And according to the figure V the possibility is shown in Figure IX and according to the figure VI the possibility is shown in Figure X. G cannot be placed at the other end otherwise C could not be placed according the position given in the statement.
|
Figure IX |
Figure X |
In the statement it is given E is sitting to the immediate right of G. So accordingly the figure VII , Figure VIII are eliminated because that position is occupied by H. So according to the figure IX the possibility is shown in Figure XI and according to the figure X the possibility is shown in Figure XII.

Q sits third to the left of U. Two persons sit between Q and W. U does not sit at any of the extreme ends of the row. R does not sit adjacent to Q and W. S sits second to the right of V. R sits fourth to the right of P. S does not sit adjacent to P. Immediate neighbor of V faces opposite direction. The one who sits at the extreme end faces opposite direction. S faces north and sits immediate left of Q. S and Q face the same direction. An immediate neighbor of U faces the same direction as U. Three of the following four are alike in a certain way based on their seating arrangement and thus form a group. Which one of the following does not belong to that group? | |||
