Six people - Komal, Lavit, Kesh, Piya, Avnit and Nisha live in a three-storey building.
The bottommost floor is numbered as 1, the floor above it as 2, and the topmost floor as 3. Each floor consists of two flats - Flat A and Flat B.
Flat B is towards the east of Flat A, on each floor.
Piya lives on the floor between the floors of Komal and Lavit.
Kesh lives in flat B and above Piya.
Komal and Lavit live in the same type of flat.
| Case 1 | | Case 2 | |
Floor 3 | Komal | Kesh | Komal | Kesh |
Floor 2 | Piya | | | Piya |
Floor 1 | Lavit | | Lavit | |
| Flat A | Flat B | Flat A | Flat B |
Komal and Lavit live in the same type of flat but not as same as Piya.
Thus, case 1 is invalid.
| Case 2 | |
Floor 3 | Komal | Kesh |
Floor 2 | | Piya |
Floor 1 | Lavit | |
| Flat A | Flat B |
Nisha lives on the floor below neither Lavit nor Piya.
Floor 3 | Komal | Kesh |
Floor 2 | Nisha | Piya |
Floor 1 | Lavit | |
| Flat A | Flat B |
Therefore, the final arrangement is:
Floor 3 | Komal | Kesh |
Floor 2 | Nisha | Piya |
Floor 1 | Lavit | Avnit |
| Flat A | Flat B |
Only statement in option (b) is true.
