1.

the ratio of copper and zinc is 8:5 in the alloy. if the weight of zinc in the alloy is 9.5 then the weight of copper in the alloy is

Answer»

zinc in 2kg of new alloy=(5/13)+(5/8)=105/104kg

coppper in 2kg of new alloy=(8/13)+(3/8)=103/104kg

ratio of zinc and copper in the resulting alloy is'

=(105/104)/(103/104)

=105/104

weight of copper in the alloy 15.2

weight of copper in the alloy = 15.2

weight of copper = 15.2

15.2 is the right answer

weight of copper in the alloy =15.2 answer
