Dinesh buys a chair marked at Rs. 5,000 at a discount of `20%` on the marked price, the rate to tax being `18%`.Calculate the tax Dinesh has to pay for this purchase. Also, find the total amount to be paid by Dinesh.

Answer

To solve the problem step by step, we will calculate the discounted price of the chair, the tax on that price, and finally the total amount Dinesh has to pay.

### Step 1: Calculate the Discounted Price
The marked price (MP) of the chair is Rs. 5,000, and the discount is 20%.

1. **Calculate the discount amount:**
\[ \text{Discount} = \text{Marked Price} \times \left(\frac{\text{Discount Percentage}}{100}\right) \]
\[ \text{Discount} = 5000 \times \left(\frac{20}{100}\right) = 5000 \times 0.20 = 1000 \]

2. **Calculate the discounted price:**
\[ \text{Discounted Price} = \text{Marked Price} - \text{Discount} \]
\[ \text{Discounted Price} = 5000 - 1000 = 4000 \]

### Step 2: Calculate the Tax on the Discounted Price
The tax rate is 18%.

1. **Calculate the tax amount:**
\[ \text{Tax} = \text{Discounted Price} \times \left(\frac{\text{Tax Rate}}{100}\right) \]
\[ \text{Tax} = 4000 \times \left(\frac{18}{100}\right) = 4000 \times 0.18 = 720 \]

### Step 3: Calculate the Total Amount to be Paid
Now, we will find the total amount Dinesh has to pay, which includes the discounted price and the tax.

1. **Calculate the total amount:**
\[ \text{Total Amount} = \text{Discounted Price} + \text{Tax} \]
\[ \text{Total Amount} = 4000 + 720 = 4720 \]

### Final Results
- Tax Dinesh has to pay: **Rs. 720**
- Total amount to be paid by Dinesh: **Rs. 4720**
