Question

How much water has to be added in 60 litre of
70% milk solution. To make it as 40% milk solution.​

Answer 1

Step-by-step explanation:

In 40 liters of milk-water mixture, the water content is 4 liters. By adding x liters of water the water content should become 20 %. So add 5 liters water to make the milk-water mixture more dilute to the extent of 20% water. Check:(4+5):(40+5) = 9/45 = 1/5 or 20 percent.
