Correct answer
Six
Why this answer is correct
-
I is at the top shelf.
-
D is not at the bottom shelf.
-
More than three shelves are between D and E. ( which means shelves between D and E are 4 , 5, 6 and so on)
-
E is above D.
-
E is immediately below A.
| Shelf | Box |
|---|---|
| 9 | I |
| 8 | A |
| 7 | E |
| 6 | |
| 5 | |
| 4 | |
| 3 | |
| 2 | D |
| 1 |
6) Two shelves are there between B and F.
-
B is above F.
-
G is immediately above H.
-
C is not at the bottom shelf.( This eliminates the Case 1 (a) )
| Case 1 (a) | Case 1 (b) | ||
|---|---|---|---|
| Shelf | Box | Shelf | Box |
| 9 | I | 9 | I |
| 8 | A | 8 | A |
| 7 | E | 7 | E |
| 6 | B | 6 | G |
| 5 | G | 5 | H |
| 4 | H | 4 | B |
| 3 | F | 3 | C |
| 2 | D | 2 | D |
| 1 | 1 | F |
The final arrangement will be:
| Case 1 (b) | |
|---|---|
| Shelf | Box |
| 9 | I |
| 8 | A |
| 7 | E |
| 6 | G |
| 5 | H |
| 4 | B |
| 3 | C |
| 2 | D |
| 1 | F |
Hence, Six shelves are above the C.
