An alloy contains only and copper and they are in the ratio of 8 :10 .if the weight of the alloy is 4 kg then the weight of copper in the alloy
Answers
An alloy contains only zinc and copper and they are in the ratio of 8 :10 if the weight of the alloy is 4 kg then the weight of copper in the alloy will be 2.222kg.
Given that the alloy contains copper and zinc only.
The ratio of the weights of zinc to copper are in the ratio 8:10
So, the weight of zinc is given as [8/(8+10)]×Total weight.
Total weight = 4kg
So, weight of zinc = (8×4)/18 = 16/9 kg = 1.778kg
The weight of copper will be = (10×4)/18 kg = 20/9 kg = 2.222kg
