Question
How many floors are in between L and R?
Study the following information carefully to answer the given question: Certain numbers of person are living on different floor of same building. P lives on floor number five. Three person lives between P and G. G lives above P. Not more than thirteen floors are there in a building. More than five persons lives between P and L and L does not live on the top floor. X lives immediate above L. Four person lives between R and X. Three persons lives between R and Z. As many persons live below Z is same as lives above M. Two persons live between Z and Y who does not live immediate above or below of R.Solution
P lives on floor number five. Three person lives between P and G. G live above P. Not more than thirteen floors are there in g building. More than five persons lives between P and L and L does not live on the top floor. X lives immediate above L. 
Four person lives between R and X. Three persons lives between R and Z. As many as persons lives below Z is same as lives above M. Two persons lives between Z and Y, who does not live immediate above or below of R.
