Given:
- Initial amount of chemical solution = 50 liters
- 5 liters of chemical solution is taken out and replaced with 5 liters of water
- This process is repeated three times

To Find:
- The amount of chemical solution left after the third replacement

Approach:
To solve this problem, we need to keep track of the amount of chemical solution at each step. Let's break down the process step by step:

Step 1:
- Initial amount of chemical solution = 50 liters
- 5 liters of chemical solution is taken out, so the remaining amount of chemical solution = 50 - 5 = 45 liters
- 5 liters of water is added to the remaining amount of chemical solution, so the total volume becomes 45 + 5 = 50 liters

Step 2:
- The remaining amount of chemical solution from step 1 = 50 liters
- 5 liters of chemical solution is taken out, so the remaining amount of chemical solution = 50 - 5 = 45 liters
- 5 liters of water is added to the remaining amount of chemical solution, so the total volume becomes 45 + 5 = 50 liters

Step 3:
- The remaining amount of chemical solution from step 2 = 50 liters
- 5 liters of chemical solution is taken out, so the remaining amount of chemical solution = 50 - 5 = 45 liters
- 5 liters of water is added to the remaining amount of chemical solution, so the total volume becomes 45 + 5 = 50 liters

Final Answer:
After the third replacement, the amount of chemical solution left is 45 liters.

Therefore, the correct option is c) 36.45L.
