Question

an alloy of copper and tin consist of 20parts of tin and 108parts of copper. find the percentage of tin and of copper in the alloy.​

Answer 1

Answer:

Step-by-step explanation:

Percentage of tin is 15.625% and copper is 84.375% in alloy

Given :

Tin = 20 parts

Copper = 108 parts

Alloy of tin and copper = (20 + 108) = 128

Now,

Find the Percentage of tin in alloy :-

tin/alloy×100 percent

20/128×100

15.625 percent

Find the Percentage of copper in alloy :-

copper/alloy×100 percent

108/128×100

84.375 percent

Hence,

Percentage of tin is 15.625% and copper is 84.375% in alloy.
