Alligation or Mixture problems
In a mixture of 45 liters, the ratio of milk and water is 4:1. How much water must be added to make the mixture ratio 3:2?
Let us assume the ratio factor is x.According to question,Quantity of milk = 4x liters and Quantity of Water = x liters.According to question,4x + x = 45? 5x = 45? x = 9 Quantity of milk = 4x = 9 x 4 = 36 litersQuantity of water = x = 9 litersLet y liters of water be added to make the ratio 3:2Then, 36/(9 + y) = 3/2 ? 72 = 27 + 3y? y = 15 litersIf you add 15 liters of water, the ratio will become 3:2.
