And now the Cardano problem with three thieves :
Three thieves want to share a barrel of wine containing 24 liters, using the barrel, and three containers 5, 11 and 13 liters.
There are not only thieves !
We have two 1 liter containers, both full, and two empty 40 and 70 cl measures.
Measure 30 cl into each of the two measures, without spilling anything.
