Question

Milk and water are mixed in a vessel A in the ratio of 5 : 2 and in a vessel B in the ratio of 8: 5. In what ratio
should quantities be taken from the two vessels so as to form a mixture, in which milk and water will be in the
ratio of 9:4?
​

Answer 1

Answer:

Working entirely with the ratios for milk, we know that the ratio of milk to water in Vessel A is 8:5. Therefore, the fraction of milk in vessel A is 8/13. Likewise, the ratio of milk to water in vessel B is 5:2. Therefore, the fraction of milk in the vessel is 5/7.
