the percentage of metals in a mine of lead ore is 60%.now the percentage of silver is 3/4% of metals and the rest is lead.if the mass of ore extracted from this mine is 8000kg the mass of lead will be how much?

• Metals = 60% So Metals = 0.6*8000= 4800
  Silver = 3/4%*4800 = 36
  Lead = 4764

• Metal= .6*8000= 4800
  Silver= 0.03/4*4800 = 36
  Lead = 8000 - 4800 - 36 = 3164 kg

• Mass of lead ore = 8000 kg
  
  ⇒ Mass of metal in lead ore = 60% 0f 8000 = 4800 kg
  
  ⇒ Mass of silver in metal
  
  =34%of 4800 = 36 kgthe mass (in kg.) of lead is 4800-36 = 4764
