From statement I and statement II alone, we cannot answer the question. On combining both statement we get, Three persons live between L and R, who lives second to the below of M. P lives above M. One person lives between P and Q. O lives immediately above R, who lives above N. The final arrangement is as follows: Either P or Q lives on the topmost floor. Therefore, both statements I and II together are not sufficient to answer the question.
