• Cost Price (CP): Purchased price
  • Selling Price (SP): Sold price
  • Market Price (MP) = Selling price + Discount Amuont
  • Profit/Gain: when SP > CP
  • Loss: when SP < CP
Gain = SP - CP
Loss = CP - SP
Gain % = [(Gain x 100)/CP]
Loss % = [(Loss x 100)/CP]
SP = [(100 + Gain %) x CP]/100 = [(100 - Loss %) x CP]/100
CP = 100/[(100 + Gain %) x SP] = 100/[(100 - Loss %) x SP]
