Answer:

40 liters

Step-by-step explanation:

since 10 percent is equivalent to 40 liters

10 percent = 40 liters

15 percent = 60 liters

20 percent = 80 liters

there are 80 liters in 20 percent salt solution, so i added 40 liters of 10 percent salt solution by 40 liters to have a 20 percent salt solution which will resulted in 80 liters.
