Task 1 - 300821 In a garden, there are two barrels of water. Jörg pours as many liters of water from the first barrel into the second barrel as the second barrel already contains. Then, he pours as many liters of water from the second barrel into the first barrel as there are in the first barrel after the previous pouring. After these two pouring processes, each of the two barrels contains exactly 24 liters of water.

Determine whether it follows uniquely from these data how many liters of water were initially in each of the two barrels! If this is the case, give these two liter amounts!
If at the end there are 24 liters in each of the two barrels and the second transfer doubled the amount of water in the first barrel, then due to $24: 2=12$ there must have been 12 liters of water in this barrel before the second transfer.

Since the total amount of water in the barrels is 48 liters, there were $48-12=36$ liters in the second barrel at this time. Furthermore, the first transfer had doubled the amount of water in the second barrel.

From this, it follows that the initial amounts of water in the barrels were uniquely determined: Since $36: 2=18$, there were 18 liters in the second barrel and $48-18=30$ liters in the first barrel.
