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?

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

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
