B. 0.22
C. 28
D. 20

Answer

To find the discount percentage at which the smartphone is being sold, we can follow these steps:

### Step 1: Identify the Marked Price and Selling Price
- **Marked Price (MP)** = Rs 25,000
- **Selling Price (SP)** = Rs 18,000

### Step 2: Calculate the Discount in Rupees
The discount can be calculated using the formula:
\[ \text{Discount} = \text{Marked Price} - \text{Selling Price} \]

Substituting the values:
\[ \text{Discount} = 25,000 - 18,000 = 7,000 \]

### Step 3: Calculate the Discount Percentage
The discount percentage can be calculated using the formula:
\[ \text{Discount Percentage} = \left( \frac{\text{Discount}}{\text{Marked Price}} \right) \times 100 \]

Substituting the values:
\[ \text{Discount Percentage} = \left( \frac{7,000}{25,000} \right) \times 100 \]

### Step 4: Simplify the Calculation
First, simplify the fraction:
\[ \frac{7,000}{25,000} = \frac{7}{25} \]

Now, calculate the percentage:
\[ \text{Discount Percentage} = \left( \frac{7}{25} \right) \times 100 \]

### Step 5: Perform the Multiplication
Calculating:
\[ \frac{7 \times 100}{25} = \frac{700}{25} = 28 \]

### Final Answer
The discount percentage at which the smartphone is being sold is **28%**.
