Question
Six persons J, K, L, M, N, and O are sitting in a
straight row facing north direction but not necessarily in the same order. Two persons sit between L and M. Neither L nor M sits at extreme ends of the row. One person sits between M and K. N sits second to the right of K. O does not sit adjacent to K. Who sits third to the left of N?Solution
