Question
In the mixture of 56 liters, the ratio of milk and water
is 3: 4. If this ratio is changed to 3: 5, then tell the amount of excess water (in liters) mixed in the mixture.Solution
Quantity of milk in the mixture = 3/7 x 56 = 24 liters Quantity of water in the mixture = 56-24 = 32 liters Let the quantity of water added in the mixture be x liters. According to the question, 24/ (32 + x) = 3/5 24 × 5 = (32 + x) × 3 120=96 + 3x 3x = 120-96 3x = 24 x = 24/3 x = 8 liters
