As per the above conditions,
Ciel is kept in the 5th numbered position.
Two water bottles are kept Voss and Ciel.
Case I
| Serial No. | Water bottle |
| 8 | |
| 7 | |
| 6 | |
| 5 | Ciel |
| 4 | |
| 3 | |
| 2 | Voss |
| 1 | |
Case II
| Serial No. | Water bottle |
| 8 | Voss |
| 7 | |
| 6 | |
| 5 | Ciel |
| 4 | |
| 3 | |

Vittel was kept immediately below Voss.
Three water bottles are kept between Vittel and Evian. So, we will eliminate Case I and continue with Case II.
Case II
| Serial No. | Water bottle |
| 8 | Voss |
| 7 | Vittel |
| 6 | |
| 5 | Ciel |
| 4 | |
| 3 | Evian |
| 2 | |
| 1 | |
Perrier is kept immediately above Aquafina.
Bisleri is kept before Perrier but after Ciel.
Thus, Dasani is kept immediately after Vittel.
| Serial No. | Water bottle |
| 8 | Voss |
| 7 | Vittel |
| 6 | Dasani |
| 5 | Ciel |
| 4 | Bisleri |
| 3 | Evian |
| 2 | Perrier |
| 1 | Aquafina |
Hence, this is the final arrangement.
As per the above arrangement, except Evian, all are kept in the even numbered position. Only Evian is kept in the 3rd numbered position.
