Rakesh has a stock of

1000 L

of pure milk. He decides to decrease the concentration to half, using the method of successive dilution, replacing

200

L

of contents by water, in each step of dilution. After the fourth dilution, he realizes that the concentration is less than the required value. Each of the contents removed during the dilution process is stored separately. He also has ample supply of water. Will he be able to make the mixture of desired concentration?

An industrial solvent of

90 %

strength is prepared and stored in a

150 L

capacity container. The container is filled to

80 %

of its capacity. It is required to decrease the concentration of the solvent in the container to less than

60 %

. For doing this, either pure water can be added to it and/or solution can be removed. But removal can only be done if there is no place for adding water. At a given time, only

10 L

of the solution can be added or removed. How many times should water be added to the solution?
