Questions & Step-by-Step Solutions

In a mixture of two liquids, if the first liquid is 60% alcohol and the second is 40% alcohol, what will be the alcohol percentage in the final mixture if equal volumes of both liquids are mixed?
  • Step 1: Identify the percentage of alcohol in the first liquid, which is 60%.
  • Step 2: Identify the percentage of alcohol in the second liquid, which is 40%.
  • Step 3: Since equal volumes of both liquids are mixed, we will find the average of the two percentages.
  • Step 4: Add the two percentages together: 60% + 40% = 100%.
  • Step 5: Divide the total by 2 to find the average: 100% / 2 = 50%.
  • Step 6: The alcohol percentage in the final mixture is 50%.
