Weight of boxes
 
I got a stack of 25 boxes. Each box has a weight.
I noticed the following property : when I remove one box (whichever I choose) of the stack, I can split the stack in 3 same weighted stacks of 8 boxes.

Prove that all boxes have the same weight.

ps : This is no homework. Just an interresting problem I found on the net :)
