There are Eleven people live on different floors in the given three building X, Y and Z' such that each of the floor of the building is occupied by the given person. Building X is immediate west of building Y, which is immediate west to building Z. in the building ground floor is numbered as 1, above it is floor 2 and so on... in the building floor-1 of building Y is immediate east of floor-1 of building X but immediate west of floor-1 of building Z and so on.
Note: A is west to B does not mean A is immediate west to B. above or below does not mean in the same building. Building Z and X has equal number of floors but more than building Y. J lives on 3rd floor and is east of E. only one floor gap is there between the floors on which E and L lives and both of them lives in the same building. D lives immediately above M in the same building but none of them lives in the same building in which J and E lives. F lives immediate east of K who lives in the same building as J. Only one floor gap is there between P and I. P lives below I. T lives to the west of N and both of them lives on an odd number floor.
Q. How many persons are livig above M in the same building ?

Options

A. Two
B. One
C. Three
D. Four

Answer

B

Explanation

Sol. J lives on 3rd floor and is east of E. only one floor gap is there between the floors on which E and L lives and both of them lives in the same building. So, from this there will be four possible cases-



F lives immediate east of K who lives in the same building as J. So, from this case 2,3,4 gets eliminated. D lives immediately above M in the same building but none of them lives in the same building in which J and E lives.

Only one floor gap is there between P and I. P lives below I. T lives to the west of N and both of them lives on an odd number floor. So, from this case-1 (b) gets eliminated. so, the final arrangement is-
