There are three containers of equal capacity and all are completely filled with mixtures of acid and water in different ratios. The ratio of acid to water in the first container is 2 : 3, in the second container the ratio is 3:7 and in the third container it is 4:11. If the mixtures of all the three containers are mixed together, what will be the ratio of acid to water in it?
