Alloy Consists Of 13 Parts Of Copper 7 Parts Of Zinc And 5 Parts Of Nickel

An alloy consists of 13 parts of copper, 7 parts of zinc and 5 parts of nickel. What is the percentage of each metal in the alloy?

Answers:

Copper = 13 parts, Zinc = 7 parts

Nickel = 5 parts

Total alloy = 13 + 7 + 5 = 25 parts

Now, percentage of copper = 13/25 × 100 = 52%

Percentage of zinc = 7/25 × 100  = 28%

And percentage of nickel = 5/25 × 100 = 20 %
