How many persons live between the floors on which Q and S live?

Options

A. Three
B. More than three
C. None
D. Two

Answer

D

Explanation

Step-1 : X lives an odd number floor above number 5. There are two persons live between X and S . B lives on odd number floor but not above and below S. There should be two possible cases.

Step 2: There are as many persons between S and U is same, as S and V. U lives below S. Q live on ground floor. There is one person between C and X and D does not sit on even numbered floor.


Final Step:- There is one person lives between C and X. D does not live an even number floor, From here we can conclude the position of V and U. A sits at even numbered floor but above on 2nd floor. So Case 2 will be cancelled.
