C. 20% Profit
D. 20% Loss

Answer

To find the gain or loss percentage for the given problem, we can follow these steps:

### Step 1: Identify the Cost Price (CP) and Selling Price (SP)
- **Cost Price (CP)** of 1 litre of milk = Rs. 20
- **Selling Price (SP)** of 1 litre of milk = Rs. 25

### Step 2: Determine if there is a Gain or Loss
Since the Selling Price (SP) is greater than the Cost Price (CP), we have a gain.

### Step 3: Calculate the Gain
- Gain = Selling Price - Cost Price
- Gain = SP - CP
- Gain = 25 - 20 = Rs. 5

### Step 4: Calculate the Gain Percentage
- Gain Percentage = (Gain / Cost Price) × 100
- Gain Percentage = (5 / 20) × 100

### Step 5: Simplify the Calculation
- Gain Percentage = (5 × 100) / 20
- Gain Percentage = 500 / 20
- Gain Percentage = 25%

### Conclusion
The gain percentage is **25%**.

### Options:
- (A) 25% Loss
- (B) 25% Profit
- (C) 20% Profit
- (D) 20% Loss

The correct answer is **(B) 25% Profit**.
