Answer:

Percentage of Copper = 82.5%
Total Parts of Alloy = 7+33 => 40
% of Zinc = \begin{gathered}\sf{\dfrac{7}{40}\times 100 = \dfrac{7}{2}\times5=17.5\%}\\\end{gathered}
40
7
×100=
2
7
×5=17.5%
% of Copper = \begin{gathered}\sf{\dfrac{33}{40}\times100=\dfrac{33}{2}\times5=82.5\%}\\\end{gathered}
40
33
×100=
2
33
×5=82.5%
Therefore, the total percent adds up to 100%.
So,
% of Zinc = 17.5%
% of Copper = 82.5%
