The alloy contains 52% brass
So in 1 kg of the alloy, there will be 52/100*1000 GMs of brass
That’s 520gms of brass.
Therefore,in 12kg of the alloy, there will be
12*520
=6240gms of brass.
Total weight of the alloy=12kg=12000gms.
Therefore weight of copper=12000-6240
=5760gms
Ans:weight of copper=5760gms and weight of brass=6240gms.
Hope it helped you.
