if 400 liters of milk and water contains 30% of milk. How much pure milk should be added to solution so that the resultant contains 60% of milk

Answer 1

Answer:

120 litres

Step-by-step explanation:

You need to add another 30% of milk so to find out what 30% is, divide 400 by 10 which is 40, then multiply it by 3 which is 120. So therefore 120 litres of pure milk must be added.
