The question given below consists of two statements

Solution

From statement I alone, P sits second to the left of Q. Only V sits to the right of Q. R sits third to the right of S. S and T sit adjacent to each other. W sits immediate left of U. We get:   K         I           G         H         D         F          E         J   Only five persons sit to the left of F. So, data given in statement I alone is sufficient to answer the question. From statement II alone, only two persons sit between W and T. W sits at extreme left end of row. S sits second to the left of P. R and P sit adjacent to each other. We get: Case 1: When G sits immediate left of H. K ____ G       H                     D         F          _____   _____   Case 2: When G sits immediate right of H. K _____  _____ H G F*       D         F* Case 3: When G sits second to the right of H. K ______  ______ H _____ G   F   D   Five, six or seven persons sit to the left of F. So, data given in statement II alone is not sufficient to answer the question. Therefore, data given in statement I alone is sufficient to answer the question while the data given in statement II alone is not sufficient to answer the question.
