Calculating Petrol Efficiency and Understanding Profit, Loss, and Discount

Calculating Petrol Efficiency

When it comes to calculating the efficiency of petrol consumption, we need to consider the total distance traveled and the amount of petrol used. In this scenario, Peter drove a total of 1000 km and used 100 liters of petrol. To calculate the rate at which the petrol was used in kilometers per liter (km/l), we can use the following formula:

Petrol Efficiency (km/l) = Total Distance / Total Petrol Used

Using the given values, we can plug in the numbers to get:

Petrol Efficiency (km/l) = 1000 km / 100 liters = 10 km/l

This means that Peter's car used 10 kilometers of petrol for every liter of fuel consumed.

Understanding Profit, Loss, and Discount

In the world of finance and commerce, understanding profit, loss, and discount is crucial for making informed decisions. In this section, we will explore the concept of discount and how it affects the price of an item.

What is a Discount?

A discount is a reduction in the price of an item, usually offered by the seller to encourage customers to make a purchase. Discounts can be offered in various forms, such as a percentage off the original price or a fixed amount deducted from the price.

Calculating Discount

Let's consider an example where a discount of 25% is given on an item that costs R450. To calculate the discount amount, we can multiply the original price by the discount percentage:

Discount Amount = Original Price x Discount Percentage

Using the given values, we can plug in the numbers to get:

Discount Amount = R450 x 25% = R450 x 0.25 = R112.50

This means that the discount amount is R112.50.

Calculating the Discounted Price

To calculate the discounted price, we can subtract the discount amount from the original price:

Discounted Price = Original Price - Discount Amount

Using the given values, we can plug in the numbers to get:

Discounted Price = R450 - R112.50 = R337.50

This means that the discounted price of the item is R337.50.

Conclusion

Calculating Petrol Efficiency: Formula and Example

Petrol Efficiency (km/l) = Total Distance / Total Petrol Used
Example: Peter drove a total of 1000 km and used 100 liters of petrol. To calculate the petrol efficiency, we can use the formula:
- Petrol Efficiency (km/l) = 1000 km / 100 liters = 10 km/l

Understanding Profit, Loss, and Discount: Key Concepts

Discount: A reduction in the price of an item, usually offered by the seller to encourage customers to make a purchase.
Discount Amount: The amount deducted from the original price to calculate the discounted price.
Discounted Price: The price of an item after applying the discount.

Calculating Discount: Formula and Example

Discount Amount = Original Price x Discount Percentage
Example: A discount of 25% is given on an item that costs R450. To calculate the discount amount, we can use the formula:
- Discount Amount = R450 x 25% = R450 x 0.25 = R112.50

Calculating the Discounted Price: Formula and Example

Discounted Price = Original Price - Discount Amount
Example: To calculate the discounted price, we can subtract the discount amount from the original price:
- Discounted Price = R450 - R112.50 = R337.50

Real-World Applications of Calculating Petrol Efficiency and Understanding Profit, Loss, and Discount

Petrol Efficiency: Calculating petrol efficiency is essential for car owners to determine the fuel efficiency of their vehicles. This information can help them plan their fuel consumption and reduce their expenses.
Profit, Loss, and Discount: Understanding profit, loss, and discount is crucial for businesses to make informed decisions about pricing, inventory management, and customer relationships. By applying these concepts, businesses can increase their revenue, reduce their losses, and build strong relationships with their customers.

Conclusion

In conclusion, calculating petrol efficiency and understanding profit, loss, and discount are essential skills in various fields, including finance and commerce. By using the formula for petrol efficiency, we can calculate the rate at which petrol is used in kilometers per liter. Similarly, by understanding the concept of discount, we can calculate the discount amount and the discounted price of an item. By applying these concepts, individuals and businesses can make informed decisions and achieve their goals.
Q&A: Calculating Petrol Efficiency and Understanding Profit, Loss, and Discount

Q: What is petrol efficiency, and why is it important?

A: Petrol efficiency refers to the rate at which petrol is used in kilometers per liter (km/l). It is an essential metric for car owners to determine the fuel efficiency of their vehicles. By calculating petrol efficiency, car owners can plan their fuel consumption, reduce their expenses, and make informed decisions about their vehicle's maintenance.

Q: How do I calculate petrol efficiency?

A: To calculate petrol efficiency, you can use the following formula:

Petrol Efficiency (km/l) = Total Distance / Total Petrol Used

For example, if you drove a total of 1000 km and used 100 liters of petrol, your petrol efficiency would be:

Petrol Efficiency (km/l) = 1000 km / 100 liters = 10 km/l

Q: What is a discount, and how is it calculated?

A: A discount is a reduction in the price of an item, usually offered by the seller to encourage customers to make a purchase. To calculate the discount amount, you can multiply the original price by the discount percentage:

Discount Amount = Original Price x Discount Percentage

For example, if a discount of 25% is given on an item that costs R450, the discount amount would be:

Discount Amount = R450 x 25% = R450 x 0.25 = R112.50

Q: How do I calculate the discounted price?

A: To calculate the discounted price, you can subtract the discount amount from the original price:

Discounted Price = Original Price - Discount Amount

For example, if the original price is R450 and the discount amount is R112.50, the discounted price would be:

Discounted Price = R450 - R112.50 = R337.50

Q: What is the difference between a discount and a sale?

A: A discount is a reduction in the price of an item, usually offered by the seller to encourage customers to make a purchase. A sale, on the other hand, is a temporary reduction in the price of an item, usually offered by the seller to clear out inventory or attract customers.

Q: Can I use a discount and a sale together?

A: Yes, you can use a discount and a sale together. For example, if an item is on sale for 20% off and you also receive a 10% discount, you can combine the two discounts to get a total discount of 30%.

Q: How do I calculate the total discount?

A: To calculate the total discount, you can add the two discounts together:

Total Discount = Discount 1 + Discount 2

For example, if you receive a 20% discount and a 10% discount, the total discount would be:

Total Discount = 20% + 10% = 30%

Q: Can I use a discount on a sale item?

A: Yes, you can use a discount on a sale item. For example, if an item is on sale for 20% off and you also receive a 10% discount, you can combine the two discounts to get a total discount of 30%.

Q: How do I calculate the total discount on a sale item?

A: To calculate the total discount on a sale item, you can add the two discounts together:

Total Discount = Discount 1 + Discount 2

For example, if you receive a 20% discount and a 10% discount, the total discount would be:

Total Discount = 20% + 10% = 30%
