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

The ratio of spirit and water in two mixtures of 20 litres and 36 litres is 3:7 and 7:5 respectively. Both the mixtures are mixed together. Now the ratio of the spirit and water in the new mixture is 

The acid and water in two vessels A and B are in the ratio 4:3 and 2:3. In what ratio should the liquid in both the vessels be mixed to obtain a new mixture in vessel C containing half acid and half water?

Two containers have acid and water mixed in the ratio 3:1 and 5:3 respectively. To get a new mixture with ratio of acid to water as 2:1, the two types of mixture have to be mixed in the ratio?

Two vessels A and B contains acid and water in the ratio 4:3 and 5:3 respectively Then the ratio in which these mixtures to be mixed to obtain a new mixture in vessel C containing acid and water in the ratio 3:2 is 

Two equal vessels are filled with the mixture of water and milk in the ratio of 3:4 and 5:3 respectively. If the mixtures are poured into a third vessel, the ratio of water and milk in the third vessel will be
