Options

A. A)15%
B. B)18%
C. C)10%
D. D)20%

Answer

To solve the problem, we need to find the profit percentage based on the given ratio of the cost price (CP) and selling price (SP).

### Step-by-Step Solution:

1. **Understand the Given Ratio**:
The ratio of the cost price to the selling price is given as \(10:11\). This means:
\[ \text{Cost Price (CP)} = 10 \text{ units} \]
\[ \text{Selling Price (SP)} = 11 \text{ units} \]

2. **Calculate the Profit**:
Profit is calculated as the difference between the selling price and the cost price:
\[ \text{Profit} = \text{SP} - \text{CP} = 11 - 10 = 1 \text{ unit} \]

3. **Calculate the Profit Percentage**:
The profit percentage is calculated using the formula:
\[ \text{Profit Percentage} = \left(\frac{\text{Profit}}{\text{CP}}\right) \times 100 \]
Substituting the values we found:
\[ \text{Profit Percentage} = \left(\frac{1}{10}\right) \times 100 = 10\% \]

4. **Conclusion**:
The profit percentage is \(10\%\).

### Final Answer:
The profit percentage is **10%**.
