Answer 1

Answer:

Weight of copper = 5760gms

Weight of brass = 6240gms

Step-by-step explanation:

Alloy of copper and brass contains = 52 % brass  

1 kg of alloy contains = $\frac{52}{100 * 1000}$ gms brass

                                        = 520 gms brass

∴ 12kg of the alloy contains = 12 * 520

                                               = 6240gms brass

Total weight of the alloy = 12kg = 12000 gms

∴ Weight of copper = 12000 - 6240

                                  = 5760 gms
