zinc by weight % equals 30%
nickel by weight % equals 45%
then copper's by weight% equals 100-75= 25%
therefore
weight of copper equals (1/4)*800
weight of copper equals 200 grams
nickel by weight % equals 45%
then copper's by weight% equals 100-75= 25%
therefore
weight of copper equals (1/4)*800
weight of copper equals 200 grams
