Q1 : You go to a tap that delivers an unlimited amount of water. You have two empty containers, one of 7 liters, the other of 11 liters. At each operation one container must be completely filled or completely emptied. How many operations are required to fill one of the containers with exactly 6 liters of water? Kindly indicate the steps
Note: The containers are shaped so irregularly that you can't measure the required amount other than by making use of the other container.
Q2 : An eight gallon container is full and both a three gallon container and a five gallon container are empty. Without using any other containers, divide the water into two equal amounts.
Note: The containers are shaped so irregularly that you can't measure the required amount other than by making use of the other containers. There are two ways to solve this puzzle.

(11 lit) (7 lit)
0 +7
+7 0
7 +7
7+4 3
-11 3
+3 0
3 +7
3+7 0
10 +7
10+1 6
thus 6 remain in the 7 lit container
