Mass of zinc ore -8000kgMass of metal -60- of 8000-4800kgMass of silver in metal -34-xD7-4800100-36 kgMass of zinc -4800-x2212-36-4764 kg-

The percentage of metals in a mine of zinc ore is $60 %$ . Now the percentage of silver is $\frac{3}{4} %$ of metals and the rest is zinc. If the mass of ore extracted from the mine is 8000 kg, then find the mass (in kg) of zinc ?

Mass of zinc ore $= 8000$ kg
Mass of metal $= 60 %$ of $8000 = 4800$ kg
Mass of silver in metal $= \frac{3}{4} \times \frac{4800}{100} = 36$ kg
Mass of zinc $= 4800 - 36 = 4764$ kg.

The percentage of metals in a mine of zinc ore is 60%. Now the percentage of silver is 34% of metals and the rest is zinc. If the mass of ore extracted from the mine is 8000 kg, then find the mass (in kg) of zinc ?

Mass of zinc ore =8000kgMass of metal =60% of 8000=4800kgMass of silver in metal =34×4800100=36 kgMass of zinc =4800−36=4764 kg.
