Question

if an alloy of a metal contains 45 % Nickel 25 percentage of Copper and rest is zinc then the weight of the zinc is 3 kg is

Answer 1

Copper + nickel +zinc =100%

45%+25%+x =100%

X=100-70=30%

So in alloy the quantity of zinc=30 %

Weight of 30%=3kg
The 100% quantity of alloy weight =10kg
Weight of nickel=4.5kg
Copper weight =2.5
