An alloy contains only zinc and copper and they are in the ratio of 7:9. If the weight of the alloy is 8kg, then find the weight of copper in the alloy.
Answers (1)
Given: Ratio of the weight of zinc and copper is 7: 9 in the alloy.
Assume the weight of zinc be 7x kg and the weight of copper be 9x kg.
7x + 9x=8 kg
16x = 8 kg
x = 0.5 kg
Hence the weight of copper is 4.5 kg.
