Answer

To find the selling price after tax for an article with a list price of Rs. 50 and a sales tax rate of 2%, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the List Price and Sales Tax Rate:**
- List Price (LP) = Rs. 50
- Sales Tax Rate (STR) = 2%

2. **Calculate the Sales Tax Amount:**
- Sales Tax Amount (STA) = (List Price × Sales Tax Rate) / 100
- STA = (50 × 2) / 100
- STA = 100 / 100
- STA = Rs. 1

3. **Calculate the Selling Price After Tax:**
- Selling Price (SP) = List Price + Sales Tax Amount
- SP = 50 + 1
- SP = Rs. 51

### Final Answer:
The selling price after tax is **Rs. 51**.
