Download Solution PDFGiven: A, B, C, D, E and F live on six different floors of the same building. The lowermost floor in the building is numbered 1, the floor above it, number 2 and so on till the topmost floor is numbered 6.
1) F lives on an even numbered floor but not 6.
2) The sum of floors on which F and C live is 3.
| Floors | Person |
| 6 | |
| 5 | |
| 4 | |
| 3 | |
| 2 | F |
| 1 | C |
3) The sum of floors on which D and F live is 7.
4) B lives immediately above A.
After positioning B and A only one position is left which will be occupied by the only person left i.e. E.
| Floors | Person |
| 6 | E |
| 5 | D |
| 4 | B |
| 3 | A |
| 2 | F |
| 1 | C |
Thus, one person live between B and F.
Hence, "Option 1" is the correct answer.
