**Title: Mastering Percentage Calculations**
1. **Question:** If a shirt originally costs ₹800 and is on sale for 25% off, what is the discounted price of the shirt?
**Answer:** To find the discounted price, we first calculate the discount amount by multiplying the original price by the percentage discount: ₹800 * 25% = ₹200. Subtract the discount from the original price to get the discounted price: ₹800 - ₹200 = ₹600. Therefore, the discounted price of the shirt is ₹600.
2. **Question:** Sara scored 85% on her math test, which had a total of 50 questions. How many questions did she answer correctly?
**Answer:** To find the number of questions Sara answered correctly, we calculate 85% of 50: 85% of 50 = 0.85 * 50 = 42. So, Sara answered 42 questions correctly.
3. **Question:** A shopkeeper marks up the price of a toy by 40% to make a profit. If the toy originally cost ₹500, what is the selling price after the markup?
**Answer:** To determine the selling price after the markup, we first find the markup amount by multiplying the original price by the percentage markup: ₹500 * 40% = ₹200. Add the markup to the original price to get the selling price: ₹500 + ₹200 = ₹700. Therefore, the selling price after the markup is ₹700.
4. **Question:** If the population of a city increased by 15% from 500,000 to 575,000, what was the increase in population?
**Answer:** To calculate the increase in population, we first find the difference between the final population and the initial population: 575,000 - 500,000 = 75,000. Therefore, the increase in population was 75,000.
5. **Question:** A laptop that originally cost ₹40,000 is now on sale for 20% off. What is the final price of the laptop after the discount?
**Answer:** To determine the final price after the discount, we calculate the discount amount by multiplying the original price by the percentage discount: ₹40,000 * 20% = ₹8,000. Subtract the discount from the original price to find the final price: ₹40,000 - ₹8,000 = ₹32,000. Hence, the final price of the laptop after the discount is ₹32,000.
