Two vessels contain spirit of 0.5 and 0.75 concentrations. If 2 lt from the first vessel and 3 lt from the second vessel are mixed, then what will be the ratio of the spirit and the water in the resultant solution?

Two vessels A and B contain solution of acid and water. In A and B the ratio of acid and water are 7 : 3 and 4 : 1, respectively. They are mixed in the ratio 1 : 2. What is the ratio of acid and water in the resulting solution?

The ratios of spirit and water in vessels A and B are 4 : 5 and 7: 11, respectively. The contents of A and B are mixed in the ratio 2 : 5. What is the ratio of spirit and water in the resulting solution?

Two vessels contain a mixture of spirit and water. In the first vessel the ratio of spirit to water is 8 : 3 and in the second vessel the ratio is 5 : 1 . A 35 litre cask is filled from these vessels so as to contain a mixture of spirit and water in the ratio of 4 : 1 . How many litres are taken from the first vessel?

Two vessels A and B contain spirit and water mixed in the ratio 5:2 and 7:6 respectively. Find the ratio in which these mixtures be mixed to obtain a new mixture in vessel C containing spirit and water in the ratio 8:5? 4 :3 (b) 3 :4 (c) 5 :6 (d) 7 :9
