Step-by-step explanation:

Given : In every gold of gram,a goldsmith mixes 0.25 grams of silver and 0.05 grams of copper.

To find : What is the percentage of gold, silver and copper in every gram of gold?

Solution :

In 1 gram of gold there is 0.25  grams of silver and 0.05 grams of copper.

So, The amount of gold in the mixture is

$G=1-(0.25+0.05)$

$G=1-0.3$

$G=0.7$

So, There is 0.7 gram of gold, 0.25 grams of silver and 0.05 grams of copper.

The amount in percentage is

$G\%=0.7\times 100=70\%$

$S\%=0.25\times 100=25\%$

$C\%=0.05\times 100=5\%$

Therefore, The percentage of gold, silver and copper in every gram of gold is 70%,25% and 5%.
