Why this answer is correct
Given: 7 boxes, namely, J, K, L, M, N, O, and P, are placed one above the other in a stack, but not necessarily in the same order.
- Box N is placed third from the bottom.
| Boxes |
|---|
| N |
- Only one box is placed between N and P.
Here, we have 2 Cases, i.e., Case 1 and Case 2.
| Boxes | |
|---|---|
| Case 1 | Case 2 |
| P | |
| N | N |
| P |
- Three boxes are placed between P and L.
| Boxes | |
|---|---|
| Case 1 | Case 2 |
| L | P |
| N | N |
| P | L |
- Box K is placed immediately below L.
Now, we can eliminate Case 2.
| Boxes |
|---|
| Case 1 |
| L |
| K |
| N |
| P |
- Box M is placed two boxes above Box K.
| Boxes |
|---|
| Case 1 |
| M |
| L |
| K |
| N |
| P |
- Box J is placed above Box O.
This is our final arrangement,
| Boxes |
|---|
| Case 1 |
| J |
| M |
| L |
| K |
| N |
| O |
| P |
Hence, the correct answer is More than four.
