Rakesh has a stock of 1000 litres of pure milk. He decides to decrease...

Given:
- Rakesh has 1000 litres of pure milk
- He wants to decrease the concentration to half using the method of successive dilution
- He replaces 200 litres 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 has ample supply of water

To find: Whether Rakesh will be able to make the mixture of desired concentration or not.

Solution:
Let's calculate the concentration of milk after each dilution step:

- After 1st dilution: 800 litres of milk and 200 litres of water => Concentration of milk = (800/1000) = 0.8
- After 2nd dilution: 600 litres of milk and 400 litres of water => Concentration of milk = (600/1000) = 0.6
- After 3rd dilution: 400 litres of milk and 600 litres of water => Concentration of milk = (400/1000) = 0.4
- After 4th dilution: 200 litres of milk and 800 litres of water => Concentration of milk = (200/1000) = 0.2

Since the concentration after the 4th dilution is less than the required value, Rakesh needs to increase the concentration by adding some of the stored contents removed during the dilution process.

Let's calculate the amount of milk required to achieve the desired concentration of 0.5:

- Concentration after 1st dilution: 0.8 => Milk required to achieve 0.5 concentration = 400 litres
- Concentration after 2nd dilution: 0.6 => Milk required to achieve 0.5 concentration = 200 litres
- Concentration after 3rd dilution: 0.4 => Milk required to achieve 0.5 concentration = 200 litres
- Concentration after 4th dilution: 0.2 => Milk required to achieve 0.5 concentration = 300 litres

Total milk required = 400 + 200 + 200 + 300 = 1100 litres

Since Rakesh has stored all the contents removed during the dilution process separately, he has enough milk to achieve the desired concentration. He can add the required amount of milk to the mixture and mix it well to get the desired concentration of 0.5.

Therefore, the answer is option (b) Possible.
