A. 18
B. 12
C. 10
D. 15

Explanation

To solve the problem of finding the approximate profit percentage per article, we can follow these steps:

### Step 1: Calculate the Cost Price (CP) and Selling Price (SP)
- **Cost Price (CP)** for 21 articles = ₹6531
- **Selling Price (SP)** for 21 articles = ₹9954

### Step 2: Calculate the Total Profit
- **Total Profit** = Selling Price - Cost Price
- Total Profit = ₹9954 - ₹6531 = ₹3423

### Step 3: Calculate the Profit Percentage
- Profit Percentage is calculated using the formula:
\[ \text{Profit Percentage} = \left( \frac{\text{Total Profit}}{\text{Cost Price}} \right) \times 100 \]
- Substituting the values:
\[ \text{Profit Percentage} = \left( \frac{3423}{6531} \right) \times 100 \]

### Step 4: Calculate the Profit Percentage Value
- Performing the division:
\[ \frac{3423}{6531} \approx 0.524 \]
- Now, multiplying by 100:
\[ \text{Profit Percentage} \approx 0.524 \times 100 \approx 52.4\% \]

### Step 5: Calculate the Profit Percentage per Article
- Since we need the profit percentage per article, we divide the total profit percentage by the number of articles:
\[ \text{Profit Percentage per Article} = \frac{52.4}{21} \approx 2.49\% \]

### Final Answer
- The approximate profit percentage per article is **2.49%** (which can be rounded to **2.5%**).
