      Question

      Two alloys are combined to create a new alloy. The first

      alloy contains 20% copper, and the second alloy contains 40% copper. If the resulting alloy has 30% copper and weighs 60 kg, what is the weight of the first alloy used?
      A 30 kg Correct Answer Incorrect Answer
      B 33 kg Correct Answer Incorrect Answer
      C 37 kg Correct Answer Incorrect Answer
      D 35 kg Correct Answer Incorrect Answer
      E 42 kg Correct Answer Incorrect Answer

      Solution

      Using alligation method the ratio of alloys = (40%-30%): (30%-20%) = 1: 1 Total weight = 60 kg the weight of the first alloy used = 60/2 = 30 kg
