Question
If all the persons in row 1 are arranged in alphabetical
order from the right end, then who among the following person sits opposite to M? Study the following information carefully and answer the below questions Twelve persons are sitting in a parallel row and opposite to each other. In row1- U, V, W, X, Y, and Z face the south. In row2- J, K, L, M, N and O face the north but not necessarily in the same order. 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. The number of persons sits to the left of U is the same as the number of persons sit 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. L sits opposite to the one who sits second to the left of Z. X and Y are not immediate neighbours.Solution
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. Â W sits second to the right of Y. Â J sits immediate left of M, none of them sits at end of the row.
Again we have, Â 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.
