Question
An alloy of copper and tin contains 85% of copper. If 28
kg of more tin is added to the alloy, the copper content gets reduced to 50%. Find the quantity of the new alloy.Solution
Ratio of copper to tin in the alloy = 17:3 Let the quantity of copper and tin in the alloy be 17x kg and 3x kg, respectively. According to question, 17x = 3x + 28 x = 2 kg So, the quantity of new alloy = 17x + 3x + 28 = 20x + 28 ⇒ 40 + 28 = 68 kg
