Answer:
This may be incomplete, i will try to answer this in a general way.
We have 4 bottles, A, B, C and D.
If A is the volume of Bottle A, B is the volume of bottle B, C is the volume of bottle C, and D is the volume of bottle D, we have that:
A = B + 3L.
D = A + 5L
C = A - 3L.
Let's solve this system the most we can (we can not fully solve the system because we have more variables than equations)
First, taking the third equation and adding 3L in both sides, we have:
C + 3L = A.
This is equivalent to the first equation, so we have that C = B.
now, we have two equations:
A = B + 3L
D = A + 5L
We can replace the first equation into the second equation and get:
D = A + 5L = (B + 3L) + 5L = B + 8L
So bottle D can hold 8L more juice than bottle B (and because bottle B and bottle C have the same volume, bottle D can hold 8L more juice than bottle C)
Now, we can order the bottles depending on the volume:
Bottle D is the one with larger volume.
Bottle A comes next.
Bottles C and B are the smaller ones, and they are together because they have the same volume.
