An article costs Rs 80. It is sold at a profit of `10%`. Find the gain amount.

Answer

To solve the problem step by step, we will follow these instructions:

### Step 1: Identify the given values
- Cost Price (CP) = Rs 80
- Profit Percentage (P%) = 10%

### Step 2: Convert the profit percentage into a fraction
- Profit Percentage can be expressed as a fraction:
\[ P\% = \frac{10}{100} = 0.10 \]

### Step 3: Calculate the profit amount
- The profit amount can be calculated using the formula:
\[ \text{Profit} = \text{Cost Price} \times \text{Profit Percentage} \]
- Substituting the values:
\[ \text{Profit} = 80 \times 0.10 = 8 \]

### Step 4: State the gain amount
