Answer: cage I

Explanation:

Given

43 gm of copper and 7 gram of other metal

Another cage has 83 gram of copper and 17 gm of other metals

Here, the percentage of copper is

For the first case


\Rightarrow (43)/(43+7)* 100=86\%

For the second case


\Rightarrow (83)/(83+17)* 100=83\%

So, the cage-I has more percentage of copper
