40M
After replacing
36M : 4W => 9:1
In the next replacement
Out of 4 Litres mixture
3.6L milk, 0.4L Water
Now, Milk => 32.4, Water => 7.6
i.e 4.26 : 1 => The current ratio of the mixture
Next 4 Litres in the above ratio
4/5.26= 0.76
0.76x4.26 = 3.239 (3.24)
32.4–3.24= 29.16 Litres of Milk

Question Analysis:
We are given that a container initially contains 40 liters of milk. From this container, 4 liters of milk is taken out and replaced by water. This process is repeated two more times. We need to determine the final amount of milk in the container.
Key Points:
- Initial amount of milk in the container: 40 liters
- Amount of milk taken out and replaced each time: 4 liters
- Number of times the process is repeated: 2
Solution:
To solve this problem, we can use the concept of mixtures. Each time 4 liters of milk is taken out and replaced by water, the percentage of milk in the container decreases. We can calculate the percentage of milk remaining in the container after each replacement and then find the final amount of milk.
Step 1:
Finding the percentage of milk after each replacement:
- After the first replacement, 4 liters of milk is taken out, so the remaining milk in the container is 40 - 4 = 36 liters.
- The percentage of milk remaining after the first replacement is (36/40) * 100 = 90%.
Step 2:
- After the second replacement, 4 liters of milk is taken out, so the remaining milk in the container is (90/100) * 36 = 32.4 liters.
- The percentage of milk remaining after the second replacement is (32.4/40) * 100 = 81%.
Step 3:
- After the third replacement, 4 liters of milk is taken out, so the remaining milk in the container is (81/100) * 32.4 = 26.244 liters.
Hence, the final amount of milk in the container is approximately 26.244 liters, which is closest to option B: 29.16 liters.
Conclusion:
After three replacements of 4 liters of milk each time, the container now contains approximately 26.244 liters of milk.
