      E Data given in all three statements I, II and III are together not sufficient to answer. Correct Answer Incorrect Answer

      Solution

      From statement I alone, as two persons sit between Q and N. One person sits between N and P. M sits 3rd to the left of P, so Q  ______  M     N   _____ P M _____  Q   P  _____ N M   N  _____ P   Q From statement II alone, as two persons sit to the right of L. Q sits third to the left of N, who sits adjacent to L, so ______   ______  Q ______ L    N   ______ Q _____  _____  N   L  ____  _____ From statement III alone, as more than two persons sit between P and R. O sits to the right of L, no possible arrangement is possible. On combining statement I and statement II, we get Q         R/O     M         N         L          P         O/R M         R/O     Q         P         L          N         O/R On combining statement I, II and III, we get Q         R         M         N         L          P         O
