Question
Who among the following lives on the seventh
floor? Study the following information carefully and answer the questions below-: Eight people Ankush, Bharti, Champa, Deeksha, Enna, Pawan, Gaurav and Harsh live in an eight storey building, but not necessarily in the same order. The lowermost floor is numbered 1 and the topmost floor is numbered 8. Ankush lives on an even-numbered floor but not on the floor numbered second or fourth. Only three floors are there between Ankush and Bharti. Only two people live between Champa and Enna. Pawan lives on a floor above Deeksha. There are equal numbers of floors between the floors on which Enna and Bharti live and between the floors on which Ankush and Enna live. Harsh lives immediately below Deeksha’s floor. Gaurav lives immediately below Ankush’s floor.Solution
Ankush lives on an even-numbered floor but not on the floor numbered second or fourth. Only three floors are there between Ankush and Bharti. Gaurav lives immediately below Ankush’s floor. 
There are equal numbers of floors between the floors on which Enna and Bharti live and between the floors on which Ankush and Enna live. Only two people live between Champa and Enna. Here, Case 1 splits into two more cases: 
Case 1 B fails here as it violates the second condition where Pawan lives on the floor above Deeksha. Thus, we get case 2 as our final arrangement.
