Answer 1

Answer

an alloy consist of 60% copper

and rest is zinc = 100% - 60% = 40%

quantity of zinc is 425g which is 40% of alloy

so, which part of 40% is 425

$\frac{425}{40} \times 100$

$\cancel {\frac{425}{40}} \times \cancel{100} = 1062.5$

$\bold \red{so, quantity \: of \: copper \: is \: 1062.5g \: or \: 1.0625kg}$
