Eight boxes of different colours namely Red, Blue, Green, Yellow, White, Grey, Brown and Black are kept in a stack (one above the other), but not necessarily in the same order.
The brown colour box is kept at the bottom of the stack.
Only three boxes are kept above the Red colour box.
Two boxes are kept between the Red colour box and the Grey colour box.
So, there are two cases possible i.e. Case 1 and Case 2.
| Case 1 | Case 2 |
| Grey |
| |
| |
| Red | Red |
| |
| |
| Grey | |
| Brown | Brown |
Five boxes are kept between the Grey colour box and the Green colour box.
A black colour box is placed immediately below the green colour box.
So, Case 2 will be invalid.
The yellow colour box is kept is immediately above the Blue colour box.
The remaining, position is occupied by the White colour box.
| Case 1 | Case 2 (Invalid) |
| Green | Grey |
| Black | |
| White | |
| Red | Red |
| Yellow | |
| Blue | |
| Grey | Green |
| Brown | Brown |
Finally, we get,
| Green |
| Black |
| White |
| Red |
| Yellow |
| Blue |
| Grey |
| Brown |
Grey is related to Brown is the odd pair out because except for this rest all have two boxes placed between them.
