D. 0.24

Answer

To calculate the profit percentage, we follow these steps:

### Step 1: Identify the Cost Price (CP) and Selling Price (SP)
- Cost Price (CP) = Rs 320
- Selling Price (SP) = Rs 400

### Step 2: Calculate the Profit
Profit is calculated using the formula:
\[ \text{Profit} = \text{Selling Price} - \text{Cost Price} \]
Substituting the values:
\[ \text{Profit} = 400 - 320 = 80 \]

### Step 3: Calculate the Profit Percentage
Profit percentage is calculated using the formula:
\[ \text{Profit Percentage} = \left( \frac{\text{Profit}}{\text{Cost Price}} \right) \times 100 \]
Substituting the values:
\[ \text{Profit Percentage} = \left( \frac{80}{320} \right) \times 100 \]

### Step 4: Simplify the Fraction
\[ \frac{80}{320} = \frac{1}{4} \]

### Step 5: Calculate the Profit Percentage
Now, substituting back into the profit percentage formula:
\[ \text{Profit Percentage} = \left( \frac{1}{4} \right) \times 100 = 25\% \]

### Final Answer
The profit percentage is **25%**.
