To determine the selling price of the electric bulb after a 10% discount, we can follow these steps:
1. Determine the initial price of the bulb: The given initial price is Rs. 150.
2. Calculate the discount amount:
- The discount is 10% of the initial price.
- To find 10% of Rs. 150, we use the formula for percentage:
[tex]\[
\text{Discount amount} = \frac{10}{100} \times 150
\][/tex]
- Simplifying this, we get:
[tex]\[
\text{Discount amount} = 0.1 \times 150 = 15
\][/tex]
3. Subtract the discount amount from the initial price to find the selling price:
- The discount amount is Rs. 15.
- To find the selling price, subtract the discount from the initial price:
[tex]\[
\text{Selling price} = 150 - 15 = 135
\][/tex]
Therefore, the actual selling price of the electric bulb after allowing a 10% discount is Rs. 135.
