It is given that,
The boxes are A, B, C, D, E, F, G, H, and I.
Five boxes are kept between F and I.
The number of boxes kept below box I is not more than three.
Box C is kept immediately above box F.
We get,
Only two boxes are kept between boxes F and B.
More than three boxes are kept between boxes B and H.
Hence, case 2 is invalid.
Box A is kept immediately above box E.
We get,
| Case 1 | Case 1.1 |
| H | H |
| C | C |
| F | F |
| A | |
| E | |
| B | B |
| A |
| E |
| I | I |
Only three boxes are kept between boxes A and D.
Hence, case 1.1 is invalid.
The final arrangement is,
Here, box B is kept above I and two boxes are kept between B and I. Similarly, box F is kept above B and two boxes are kept between F and B.
