A friend of mine in London has a very nice cellar. He has two large barrels in the cellar. He has two large barrels in the cellar. The larger barrel is mostly empty. But the smaller barrel is only 5/6th full of wine while it can hold 536 liters.
Supposing he empties the smaller barrel and fills the bigger barrel to find that the wine fills only 4/9ths of it, how much wine would the larger barrel hold when full?
