An alloy of copper and tin contains 65% of copper. If 12 kg of more tin is added to the alloy, the copper content gets reduced to 50%. Find the quantity of the new alloy.
Ratio of copper to tin in the alloy = 13:7 Let the quantity of copper and tin in the alloy be 13x kg and 7x kg, respectively. According to question, 13x = 7x + 12 x = 2 kg So, the quantity of new alloy = 13x + 7x + 12 = 20x + 12 ⇒ 40 + 12 = 52 kg
