Question: If a container has 40 liters of a solution that is 25% salt, how much salt is in the container?

Options:

Correct Answer: 10 liters

Solution:

Salt in the solution = 25% of 40L = 0.25 * 40 = 10 liters.

If a container has 40 liters of a solution that is 25% salt, how much salt is in the container?

If a container has 40 liters of a solution that is 25% salt, how much salt is in the container?

Step 1: Understand that the solution is 25% salt. This means that for every 100 liters of solution, there are 25 liters of salt.
Step 2: We have a total of 40 liters of solution.
Step 3: To find out how much salt is in the 40 liters, we need to calculate 25% of 40 liters.
Step 4: Convert 25% to a decimal. 25% is the same as 0.25.
Step 5: Multiply the total volume of the solution (40 liters) by the decimal (0.25).
Step 6: Calculate 0.25 * 40 = 10 liters.
Step 7: Therefore, there are 10 liters of salt in the container.
