Question

an alloy of Copper and Tin consists of 20 parts of tin and 108 points of copper find the percentage of tin and copper in the alloy

Answer 1

Hello mate,

Here is your answer,

Given :-

Total number of Tin part = 20 parts.

Total number of Copper parts = 108 parts

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

Now,

We have to find the Percentage of tin in alloy :-

% of tin =20/128×100%

                     =1282000​%

                      =15.625%​ 

We have to Find the Percentage of copper in alloy :-

% of copper​=108/128×100​%

                    =84.375%​ 

Hence,

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