We have, U sits opposite to the one who sits second to the left of O. Only two persons sit between K and O. K sits to the left of O. From the above condition, there are three possibilities. Again we have, The number of persons sit to the left of U is the same as the number of persons sits to the right of Y. W sits second to the right of Y. J sits immediate left of M, none of them sits at end of the row. Again we have, L sits opposite to the one who sits second to the left of Z. X and Y are not immediate neighbours. From the above condition, case2 and case3 get eliminated. Case1 shows the final arrangement.
