## PROFIT AND LOSS

**General Rules**

**Cost Price (CP)**: The price at which an article is purchased is called the cost price of the article.

**Selling Price (SP)**: The price at which an article is sold is called the selling price of the article.

**Profit or Gain**: If SP is greater than CP, the seller is said to have profit or gain.

Clearly, Profit = (SP)-(CP)

**Loss**: If SP is less than the cost price, the seller is said to have a loss.

Clearly, Loss = (CP)-(SP)

Loss or gain are always reckoned on cost price.

Profit on 100 is Profit Percent.

Loss on 100 is Loss Percent.

**Points to Remember**

Profit = SP-CP | Loss = CP-SP> |

Profit% = (Profit x 100/CP) | Loss% = (Loss x 100/CP) |

SP = (100 + Profit%/100) x CP | SP = (100 - Loss%/100) x CP |

CP = (100/100 + Profit%) x SP | CP = (100/100 = Loss%) x SP |

If an article is sold at a Profit of 20% then SP = (120% of CP) | |

If an article is sold at a loss of 20% then SP = (80% of CP) |
