Answer:
Total Parts of Alloy = 13+7+5 => 25
% of Copper = \begin{gathered}\sf{\dfrac{13}{25}\times 100 = 13\times4=52\%}\\\end{gathered}
25
13
×100=13×4=52%
% of Zinc = \begin{gathered}\sf{\dfrac{7}{25}\times100=7\times4=28\%}\\\end{gathered}
25
7
×100=7×4=28%
% of Nickel = \begin{gathered}\sf{\dfrac{5}{25}\times100=5\times4=20\%}\\\end{gathered}
25
5
×100=5×4=20%
Therefore, the total percent adds up to 100%.
So,
% of Copper = 52%
% of Zinc = 28%
% of Nickel = 20%
