Questions & Step-by-Step Solutions
In a mixture of two liquids, if the first liquid is 40% and the second is 60%, what is the overall percentage of the first liquid in a 50-liter mixture containing 20 liters of the first liquid?
Step 1: Identify the total volume of the mixture, which is 50 liters.
Step 2: Identify the volume of the first liquid in the mixture, which is 20 liters.
Step 3: To find the percentage of the first liquid, use the formula: (Volume of first liquid / Total volume of mixture) * 100.
Step 4: Substitute the values into the formula: (20 liters / 50 liters) * 100.
Step 5: Calculate the fraction: 20 divided by 50 equals 0.4.
Step 6: Multiply 0.4 by 100 to get the percentage: 0.4 * 100 = 40%.
Step 7: Conclude that the overall percentage of the first liquid in the mixture is 40%.
