See, in the alloy, there will be 63kg zinc which is 45% of the total alloy.
So 45% of total weight = 63kg
100% of alloy = 63*(100/45) = 140kg
mass of copper to be added = 140 - 63 = 77kg
So you need to add 77kg of copper
So 45% of total weight = 63kg
100% of alloy = 63*(100/45) = 140kg
mass of copper to be added = 140 - 63 = 77kg
So you need to add 77kg of copper
