Actual cost of the product is Rs 100, further the shopkeeper increase the marked price by 10%. He gives 10% commission on the sale of that product. Then, the selling price of the product?

Options

A. Rs 100
B. Rs 101
C. Rs 99
D. None of these

Answer

To find the selling price of the product, we will follow these steps:

### Step 1: Determine the Marked Price (MP)
The actual cost price (CP) of the product is Rs 100. The shopkeeper increases the marked price by 10%.

\[ \text{Marked Price (MP)} = \text{CP} + 10\% \text{ of CP} \]
\[ \text{MP} = 100 + \left(\frac{10}{100} \times 100\right) \]
\[ \text{MP} = 100 + 10 = 110 \]

### Step 2: Calculate the Discount
The shopkeeper gives a 10% discount on the marked price.

\[ \text{Discount} = 10\% \text{ of MP} = \frac{10}{100} \times 110 \]
\[ \text{Discount} = 11 \]

### Step 3: Calculate the Selling Price (SP)
The selling price is calculated by subtracting the discount from the marked price.

\[ \text{Selling Price (SP)} = \text{MP} - \text{Discount} \]
\[ \text{SP} = 110 - 11 = 99 \]

### Final Answer
The selling price of the product is Rs 99.
