Question

43 grams of copper and 7grams other metals in a birdhouse, 83 grams of copper and 17 grams of other metals. Which one has more copper?

Answer 1

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
