How many persons sit between J and O?

Options

A. One
B. Two
C. Three
D. None

Answer

D

Explanation

Step-1: J sits 10m. to the left of K who is walking 5m. Towards south direction than take right turn and walk 10m. then again take a right turn and walk to reach J. From the statement M sits 5m. to the immediate left of L we came to know that because of equal distance between two persons is same there must be 1 person is sitting between J and K.

Step-2: M sits 5m. to the immediate left of L, who is 15m. from K. So M and L could be left of K or right of K. there must be two possibilities. And 15m. from K which means there are two persons who are sitting between K and L.

Step-3: N starts walking towards north after walking of 7m. he takes a left turn than after 10m. of walking he reached point Y than turn left and reach O. N is not an immediate neighbor of M. From this statement Case-1 is not possible so it has eliminated.
