The question given below consists of two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read all the statements and answer the question. Eight persons D, E, F, G, H, I, J, and K sit in a linear row and face towards the north direction however not necessarily in the same order. The distance between any two adjacent persons is same. How many persons sit to the left of F? Statement I: D sits second to the left of E. Only J sits to the right of E. F sits third to the right of G. G and H sit adjacent to each other. K sits immediate left of
I. Statement II: Only two persons sit between K and H. K sits at extreme left end of row. G sits second to the left of
D. F and D sit adjacent to each other.

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.
