To find the selling price of a calculator when a discount of 5% is allowed on its marked price of Rs. 200, follow these steps:
1. Determine the discount amount: The first step is to calculate the discount amount. The discount is 5% of the marked price.
- Formula to calculate the discount amount:
[tex]\[
\text{Discount Amount} = \left( \frac{\text{Discount Percentage}}{100} \right) \times \text{Marked Price}
\][/tex]
- Plug in the values:
[tex]\[
\text{Discount Amount} = \left( \frac{5}{100} \right) \times 200
\][/tex]
- Calculate the result:
[tex]\[
\text{Discount Amount} = 0.05 \times 200 = 10 \text{ Rs}
\][/tex]
2. Calculate the selling price: After determining the discount amount, subtract it from the marked price to find the selling price.
- Formula to calculate the selling price:
[tex]\[
\text{Selling Price} = \text{Marked Price} - \text{Discount Amount}
\][/tex]
- Plug in the values:
[tex]\[
\text{Selling Price} = 200 - 10
\][/tex]
- Calculate the result:
[tex]\[
\text{Selling Price} = 190 \text{ Rs}
\][/tex]
So, the discount amount is Rs. 10, and the selling price after applying the discount is Rs. 190.
