Options

A. 810
B. 890
C. 900
D. 870

Answer

To find the selling price of the chair after applying the discount, we can follow these steps:

### Step 1: Identify the Marked Price and Discount Percentage
The marked price (MP) of the chair is given as Rs 900, and the discount percentage is 10%.

### Step 2: Calculate the Amount of Discount
To find the amount of discount, we can use the formula:
\[ \text{Discount} = \left(\frac{\text{Discount Percentage}}{100}\right) \times \text{Marked Price} \]
Substituting the values:
\[ \text{Discount} = \left(\frac{10}{100}\right) \times 900 = 0.10 \times 900 = 90 \]

### Step 3: Calculate the Selling Price
The selling price (SP) can be calculated by subtracting the discount from the marked price:
\[ \text{Selling Price} = \text{Marked Price} - \text{Discount} \]
Substituting the values:
\[ \text{Selling Price} = 900 - 90 = 810 \]

### Final Answer
The selling price of the chair is Rs 810.
