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 %
