If the profit on selling an article is Rs.50 and the cost price of the article is Rs.500, then the profit percentage is ___________.

Explanation

To find the profit percentage, we can use the formula:

\[ \text{Profit Percentage} = \left( \frac{\text{Profit}}{\text{Cost Price}} \right) \times 100 \]

Given:
- Profit = Rs. 50
- Cost Price (CP) = Rs. 500

Now, let's calculate the profit percentage step by step.

### Step 1: Identify the Profit and Cost Price
We have:
- Profit = Rs. 50
- Cost Price = Rs. 500

### Step 2: Substitute the Values into the Formula
We substitute the values into the profit percentage formula:

\[ \text{Profit Percentage} = \left( \frac{50}{500} \right) \times 100 \]

### Step 3: Calculate the Fraction
Now, calculate the fraction:

\[ \frac{50}{500} = 0.1 \]

### Step 4: Multiply by 100
Next, multiply the result by 100 to find the profit percentage:

\[ 0.1 \times 100 = 10 \]

### Step 5: Conclusion
Thus, the profit percentage is:

\[ \text{Profit Percentage} = 10\% \]

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