Correct Answer: 50.7
Explanation:
Step 1: Understand the setup
Step 2: Calculate milk in each bottle
Bottle 1: Milk = (5 / 12) × 1 = 0.4167 litres Bottle 2: Milk = (7 / 16) × 1 = 0.4375 litres Bottle 3: Milk = (2 / 3) × 1 = 0.6667 litres
Total milk = 0.4167 + 0.4375 + 0.6667 = 1.5209 litres
Total mixture = 3 litres (since 1 litre from each bottle)
Step 3: Calculate percentage of milk in the mixture
Percentage of milk = (Total milk / Total mixture) × 100 = (1.5209 / 3) × 100 ≈ 50.7%
Answer: Approximately 50.7% of the mixture is milk.
By averaging the ratios by volume, weighted equally, we calculate the final milk concentration in the combined mixture.
