Answer

To find the total price increase of an article originally priced at Rs. 100 after two successive percentage increases (first by 20% and then by 10%), we can follow these steps:

### Step-by-Step Solution:

1. **Calculate the first increase (20% of Rs. 100)**:
- The first increase is 20% of Rs. 100.
- Calculation:
\[ \text{Increase} = \frac{20}{100} \times 100 = 20 \]
- New price after the first increase:
\[ \text{New Price} = 100 + 20 = 120 \]

2. **Calculate the second increase (10% of Rs. 120)**:
- The second increase is 10% of the new price (Rs. 120).
- Calculation:
\[ \text{Increase} = \frac{10}{100} \times 120 = 12 \]
- New price after the second increase:
\[ \text{New Price} = 120 + 12 = 132 \]

3. **Calculate the total increase in price**:
- The original price was Rs. 100, and the final price is Rs. 132.
- Total increase:
\[ \text{Total Increase} = 132 - 100 = 32 \]

### Final Answer:
The total price increase is **Rs. 32**.
