On which floor does A live?

Solution

From 1, 2, 3, 6 From 3, 4, 5 K date + 1 = E date E lives above the one with date 15^th. Thus e’s date cannot be 15^thand hence K’s date cannot be 14^th B – 9/10/11/12 K -13^th/14^th/15^th Floors - K/E -- - - - E/K From 5 we know, K has to be with April. It can either be on floor 10 or 4. We also know that there are 4 people between K and E. If we set K on 10^thfloor, the only possible position for E is 5^thfloor which is already occupied by H. Thus, K will be at floor 4 with E on 9^thfloor. Combining with 4, person with booking on 15^thlives on 8 floor. Thus, possible date for K is only 13^th. And thus, E’s date is 14^th. From 6 and 7, we know that people having bookings in Oct occupy floors above 6and have only 1 floor/person gap, which is possible only for floor 7 and 9. From 5 and 7, B and I can occupy floor 12 and 6. But according to 3, B date = B floor. Thus, B is at 12^thfloor. From 8, F stays between E and C. Only possible outcome is E, F and C on 9^th, 8^thand 7^thfloor. From 10 and 7 we know that there are 5 people between B and I and their months are same and must have 31days.Cannot be July (from table. Only 1 person between both July). Cannot be May (Only 1 person between both May.) Thus. March is the month for B and I. From table and point 10, July fits only for floors 5 and 3 From 11. There are 4 floors between 19^thand 10^ththerefore, 10^thon 7 floor. 20^thnot possible for H according to 10.Thus combining 10 and 11,we get that the person with booking on 20^thlives on 10 floor and the one having booking on 17^thlives on floor 11. From 12 we know, person with booking on 18^thlives immediately above the person having booking on 11^th. Combining 8, Suitable position for J and the month of June (6 person gap). From 10, we know that L doesn’t go on 16^th. Thus, the table obtained is
