Profit % = (Profit / CP) × 100
Loss Percentage:
Loss % = (Loss / CP) × 100
These formulas are widely used in solving numerical problems in this chapter.
Selling Price Formulas
Students also learn how to calculate the selling price when profit or loss percentage is given.
- SP = CP × (100 + Profit %) / 100
- SP = CP × (100 − Loss %) / 100
These formulas are essential for solving exam-based questions quickly and accurately.
