Question

From a cask of milk containing 30 litres, 6 litres are drawn out and the cask is filled up with water.If the same process is repeated a second, then a third time, what will be the number of litres of milk left in the cask?(litres)

Answer 1

12 litres of milk is left in the cask

Answer 2

Answer: 15.36 liters

Step-by-step explanation:

30 liters = (24 milk +6 water)

so now from this 30liters 6 liters is drawn =$\frac{6}{30}=0.2$

then left over is 0.8(24 milk + 6 water)= 19.2 liters milk (for second time)

so once again 0.8(19.2)=15.36 liters milk
