An article bought for Rs 450 is sold at a loss of 20%. Find its selling price.

Answer

To find the selling price (SP) of an article that was bought for Rs 450 and sold at a loss of 20%, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Cost Price (CP)**:
- The cost price of the article is given as Rs 450.
- \( CP = 450 \)

2. **Identify the Loss Percentage**:
- The loss percentage is given as 20%.
- \( \text{Loss Percentage} = 20\% \)

3. **Calculate the Selling Price (SP)**:
- The formula to calculate the selling price when there is a loss is:
\[ SP = \left( \frac{100 - \text{Loss Percentage}}{100} \right) \times CP \]
- Substitute the values into the formula:
\[ SP = \left( \frac{100 - 20}{100} \right) \times 450 \]
- Simplify the expression:
\[ SP = \left( \frac{80}{100} \right) \times 450 \]
- Convert the fraction:
\[ SP = 0.8 \times 450 \]
- Calculate the multiplication:
\[ SP = 360 \]

4. **Conclusion**:
- The selling price of the article is Rs 360.

### Final Answer:
The selling price (SP) of the article is Rs 360.
