To find the selling price (SP) and cost price (CP) when the profit or loss percentage is given, you can use the following formulas:
- Profit (P) Percentage:
- If the profit percentage is given, use this formula:
- SP = CP + (Profit Percentage * CP / 100)
- To find CP when profit percentage is given, rearrange the formula:
- CP = SP / (1 + (Profit Percentage / 100))
- Loss (L) Percentage:
- If the loss percentage is given, use this formula:
- SP = CP – (Loss Percentage * CP / 100)
- To find CP when loss percentage is given, rearrange the formula:
- CP = SP / (1 – (Loss Percentage / 100))
