The price of a product after getting 20% discount is Rs 3,024 which includes 5% tax on selling price. What was the marked price (in Rs) of the product?

Options

A. 3780
B. 2742
C. 3600
D. 3456

Answer

To find the marked price of the product, we can follow these steps:

### Step 1: Understand the relationship between marked price, selling price, and tax
Let the marked price be denoted as \( MP \). When a discount of 20% is applied to the marked price, the selling price (before tax) can be calculated as:
\[ SP = MP - (20\% \text{ of } MP) = MP - 0.2 \times MP = 0.8 \times MP \]
