A question is given, followed by two statements

Solution

From statement I alone, T sits third to the right of R. Only two persons sit between R and X. S sits immediate left of V. We get: Case 1: X         S         V         R         U/W    W/U    T          Case 2: X         U/W    W/U    R         S         V         T          As, from the information given in statement I, we cannot determine the person, who sits immediate right of X. So, data in statement I alone is not sufficient to answer the question. From statement II alone, V sits third to the left of U. T sits immediate right of U. X sits second to the left of V. We get: X         _____V         ______           ______           U         T The positions of R, S and W, cannot be determined. So, we cannot determine the person, who sits immediate right of X. Combining statements I and II together, we get: X         S         V         R         W        U         T So, combining statements I and II together, we get S sits immediate right of X. Therefore, data in statements I and II together is sufficient to answer the question
