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, boxes F and C are kept somewhere above box A.
