Question 7
Each bucket retains up to its labeled capacity. Extra water is split equally among its outgoing branches. S drains completely; unnumbered terminal buckets collect the incoming water. In the example,200 liters enter S; the 40,20,20-liter buckets finish full, M has 80 liters and N 40.

A different system below starts empty and receives 200 liters through S. No water escapes the system. When flow stops, how much water is in A?
