Answer

To find the loss percentage when articles are bought at Rs 10 each and sold at Rs 7 each, we can follow these steps:

### Step 1: Identify the Cost Price (CP) and Selling Price (SP)
- Cost Price (CP) = Rs 10
- Selling Price (SP) = Rs 7

### Step 2: Calculate the Loss
- Loss = Cost Price - Selling Price
- Loss = 10 - 7 = Rs 3

### Step 3: Calculate the Loss Percentage
- The formula for Loss Percentage is:
\[ \text{Loss Percentage} = \left( \frac{\text{Loss}}{\text{Cost Price}} \right) \times 100 \]
- Substituting the values:
\[ \text{Loss Percentage} = \left( \frac{3}{10} \right) \times 100 \]

### Step 4: Simplify the Calculation
- Calculate the fraction:
\[ \frac{3}{10} = 0.3 \]
- Now multiply by 100:
\[ 0.3 \times 100 = 30 \]

### Step 5: Conclusion
- The loss percentage is 30%.

### Final Answer:
- The loss percentage is **30%**.
