Directions: Study the following information carefully and answer the questions given below.
Nine students viz., A, B, C, D, E, W, X, Y and Z have cleared the class test and are ranked from 1 to 9. They are standing in the ground at a certain distance. No two persons secured the same rank.Note: The distance between two students is twice of the lowest rank among them. For example, if P is the first rank and Q is the second rank, the distance between them is 4m. X is to the west of A and is the immediate previous rank of D who is to the north of X. The number of persons ranked between D and W is an odd prime number where no one ranks after W who is to the east of D. E ranks exactly between D and W and is to the south of Y. C stands to the south of W and ranks before E. Z stands to the west of C and ranks after Y. The direction of Y from E is same as the direction of B from Z. B holds the immediate next rank to E and stands to the west of E. C neither holds the first rank nor before X. Y holds the rank after A but before E. Z holds the rank after B and is four ranks after C. Y is not secured the first rank.
Q. In which direction is C standing with respect to A?
A. North-east
B. South-east
C. North-west
D. South-west
E. Cannot be determined
Q. How many persons rank after E in the final arrangement?
A.1
B.2
C.3
D.4
E. None
Q. What is the approximate shortest distance between D and A and who ranks according to that value?
A. 5, Y
B. 7, E
C. 5, B
D. 7, B
E. 5, E
Sol:
Following the statements given above, the rank, distance and the directions of each student are obtained as follows.
