A mixture contains milk and water in the ratio 5:3. If 16 liters of the mixture are removed and replaced with water, the ratio becomes 3:5. What was the original quantity?

✓ Correct Answer: Option A

Let total = 8x. Milk = 5x, Water = 3x. After removing 16L: milk = 5x − 10, water = 3x − 6 + 16 = 3x+10. Ratio 3:5: 5(5x−10) = 3(3x+10). 25x−50 = 9x+30. 16x = 80. x = 5. Total = 40L.
