64 litres of a mixture, which has milk and water in the ratio 5 : 3 is mixed with 36 litres of a mixture, which has water and milk in the ratio 1 : 2. What is the percentage of water in the resultant mixture?
Explanation:
Solution 1: 64 litres of a mixture, which has milk and water in the ratio 5 : 3 Quantity of milk = 58× 64 = 40 litres Quantity of water = 38× 64 = 24 litres
Solution 2: 36 litres of a mixture, which has milk and water in the ratio 2 : 1 Quantity of milk = 23× 36 = 24 litres Quantity of water = 13× 36 = 12 litres
Total quantity of milk in the final mixture = 40 + 24 = 64 liters Total quantity of water in the final mixture = 24 + 12 = 36 liters
∴ Percentage of water = 3636+64 × 100% = 36%
Hence, 36.
