The Milkman Is At The Door
A milkman has an 8 liter jar, a 5 liter jar, and a 3 liter jar. Currently, the 8 liter jar is full of milk while the 5 liter and the 3 liter jars are empty. He reaches a house and a woman asks for 4 liters of milk. However, the milkman has no 4 liter jar and has no markings in the existing jars.
Can the milkman pour milk into the jars in such a way that he can sell 4 liters of milk to the woman without throwing any milk away or giving her extra milk?
