Question

the ratio of milk to water in a mixture is 2:3 and the ratio of water to milk in another mixture is 3:4 . if 70 liters of each type of mixture is added to 100 liters of pure milk, what will be the ratio of milk and water now?

Answer 1

70 L of 2:3 mixture contains 2/5th part milk and 3/5 th part water i.e. 28 L milk and 42 L water

Similarly 70 L of 3:4 mixture contains 30 L milk and 40 L water

Thus total volume of water in final mixture
= 42 + 40 = 82 L

And total volume of milk in final mixture
= 28 + 30 + 100 = 158 L

Therefore ratio of milk to water = 158:82 = 79:41
