Answer

Let's solve the problem step by step.

### Step 1: Calculate the Discount
The formula for calculating the discount is:
\[ \text{Discount} = \text{MRP} \times \left(\frac{\text{Discount Percentage}}{100}\right) \]
Given:
- MRP = 12,000
- Discount Percentage = 30%

Substituting the values:
\[ \text{Discount} = 12000 \times \left(\frac{30}{100}\right) = 12000 \times 0.30 = 3600 \]

**Discount = 3600**

### Step 2: Calculate the Selling Price
The selling price can be calculated by subtracting the discount from the MRP:
\[ \text{Selling Price} = \text{MRP} - \text{Discount} \]
Substituting the values:
\[ \text{Selling Price} = 12000 - 3600 = 8400 \]

**Selling Price = 8400**

### Step 3: Calculate CGST and SGST
The GST is divided equally into CGST and SGST. Since the total GST percentage is 18%, each will be:
\[ \text{CGST} = \text{SGST} = \frac{\text{GST Percentage}}{2} = \frac{18}{2} = 9\% \]

Now, calculate CGST:
\[ \text{CGST} = \text{Selling Price} \times \left(\frac{\text{CGST Percentage}}{100}\right) \]
Substituting the values:
\[ \text{CGST} = 8400 \times \left(\frac{9}{100}\right) = 8400 \times 0.09 = 756 \]

Since CGST and SGST are equal:
\[ \text{SGST} = 756 \]

**CGST = 756, SGST = 756**

### Step 4: Calculate the Amount of Bill
The amount of the bill is the sum of the Selling Price, CGST, and SGST:
\[ \text{Amount of Bill} = \text{Selling Price} + \text{CGST} + \text{SGST} \]
Substituting the values:
\[ \text{Amount of Bill} = 8400 + 756 + 756 = 9912 \]

**Amount of Bill = 9912**

### Summary of Results
- Discount = 3600
- Selling Price = 8400
- CGST = 756
- SGST = 756
- Amount of Bill = 9912
