Question: Create poster to teach profit and loss
1. **Problem Statement:** We want to understand the concepts of profit and loss in business transactions.
2. **Key Formulas:**
- Profit = Selling Price (SP) - Cost Price (CP)
- Loss = Cost Price (CP) - Selling Price (SP)
- Profit Percentage = \(\frac{\text{Profit}}{\text{Cost Price}} \times 100\%\)
- Loss Percentage = \(\frac{\text{Loss}}{\text{Cost Price}} \times 100\%\)
3. **Important Rules:**
- If SP > CP, there is a profit.
- If SP < CP, there is a loss.
- If SP = CP, there is no profit or loss.
4. **Example:**
Suppose an item costs $100$ and is sold for $120$.
- Profit = $120 - 100 = 20$
- Profit Percentage = $\frac{20}{100} \times 100\% = 20\%$
5. **Another Example:**
If the item costs $150$ and is sold for $130$.
- Loss = $150 - 130 = 20$
- Loss Percentage = $\frac{20}{150} \times 100\% \approx 13.33\%$
6. **Summary:**
- Always compare SP and CP to determine profit or loss.
- Use the formulas to calculate exact amounts and percentages.
- Understanding these helps in making better business decisions.
