Question

an alloy consists of 13 parts of copper 7 parts of zinc and 5 parts of Nickel find the percentage of copper in an alloy​

Answer 1

Answer:

Total parts = 13 + 7 + 5 = 25 .

Percentage composition of copper = 13/25 × 100 = 52%

Percentage composition of zinc = 7/25*100=28%

Percentage composition of nickel = 5/25×100 = 20% .

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Question:

_____________

An alloy consists of 13 parts of copper, 7 parts of Zinc and 5 parts of Nickel. Find the percentage of copper in the alloy.

Explanation:

________________

Parts of Copper in the alloy = 13 parts

Parts of Zinc in the alloy = 7 parts

Parts of Nickel in the alloy = 5 parts

Hence,

Total parts present in the alloy

= ( 13 + 7 + 5 ) parts

= 25 parts

Now,

% of Copper in the alloy

= 13 × 100 %

25

= 13 × 4 %

= 52 %

Hence, % of Copper in the alloy is 52 %
