Two containers of the same volume are 30% and 60% full of water, respectively. They are then filled completely with milk. If the contents of both containers are mixed in a larger vessel, what is the percentage of milk in the final mixture?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 55%.
Let the volume of each container = 100 litres
Container 1: Water = 30 litres, Milk = 70 litres
Container 2: Water = 60 litres, Milk = 40 litres
Total water = 30 + 60 = 90 litres
Total milk = 70 + 40 = 110 litres
Total volume = 100 + 100 = 200 litres
Percentage of milk in mixture = (110/200) × 100 = 55%
