Three vessels whose capacities are in the ratio of 3 : 2 : 1 are completely filled with milk mixed with water. The ratio of milk and water in the mixture of vessels are 5 : 2, 4 : 1 and 4 : 1 respectively. Taking $$\frac{1}{3}$$ of first, $$\frac{1}{2}$$ of second and $$\frac{1}{7}$$ of third mixture, a new mixture kept in a new vessel is prepared. The percentage of water in the new mixture is -
