An alloy contains alluminium and zinc in the ratio 5 : 3 and another alloy contains alluminium and copper in the ratio 8 : 5. If equal weights of both the alloys are mixed together, then what would be the weight of copper per kg in the resulting alloy?

Ratio of the metals in the new alloy Al : Zn : Cu = (5/8 + 8/13) : (3/8) : (5/13) = (129/104) : (3/8) : (5/13) = 129 : 39 : 40 Therefore the copper in the new alloy = 40/208 = 5/26 kg per kg of the alloy
