Solution(By Examveda Team)

The zinc equivalent calculation is as follows :
ZnEq = 100((Ag price in (g) × Ag Grade) + (Pb Price*2204.6 × Pb Grade(%)/100) + (Zn Price*2204.6 × (Zn Grade(%)/100))/Zn Price*2204.6). The numbers may not add due to rounding.
Zn - equivalent is related to Heavy metal toxicity.
