Introduction

In this article, we'll break down a practical math problem involving discounts and expenses encountered during a shopping trip. Specifically, we'll examine a scenario where Ali purchases food items from a super store that offers special discounts on fruits and other items. This exercise will help us understand how to calculate discounts, determine the final prices after applying these discounts, and compute the total expenses. Understanding these calculations is crucial for everyday financial literacy and effective budgeting. Let's dive into the details of Ali's shopping experience and solve the related mathematical questions.

Problem Statement

Ali visits a super store and buys several food items. The store has a special discount offer: a 20% discount on all fruit items and a 15% discount on all other items. Ali purchases bananas worth Rs. 150 and apples worth Rs. 230. Additionally, he buys other items totaling Rs. 510. Our task is to calculate the discount Ali receives on each category of items and the final amount he needs to pay. This involves applying percentages, performing subtractions, and summing up the costs.

Discount on Fruit Items

First, let's calculate the total cost of the fruit items. Ali bought bananas for Rs. 150 and apples for Rs. 230. To find the total cost of the fruits, we simply add these amounts together:

Total cost of fruits = Cost of bananas + Cost of apples Total cost of fruits = Rs. 150 + Rs. 230 Total cost of fruits = Rs. 380

Now, we know that the super store offers a 20% discount on fruit items. To calculate the discount amount, we need to find 20% of the total cost of the fruits. We can do this by multiplying the total cost by 20% (or 0.20):

Discount on fruits = 20% of Rs. 380 Discount on fruits = 0.20 * Rs. 380 Discount on fruits = Rs. 76

Thus, Ali receives a discount of Rs. 76 on the fruit items. This calculation showcases how percentage discounts can significantly reduce the overall cost of purchases, making it a beneficial offer for customers. The ability to quickly calculate such discounts is a valuable skill in everyday shopping scenarios, helping consumers make informed decisions and manage their budgets effectively.

Discount on Other Items

Next, we need to calculate the discount on the other items Ali purchased. The problem states that Ali bought other items worth Rs. 510, and there is a 15% discount applicable to these items. To calculate the discount amount, we need to find 15% of Rs. 510. This can be done by multiplying the total cost of the other items by 15% (or 0.15):

Discount on other items = 15% of Rs. 510 Discount on other items = 0.15 * Rs. 510 Discount on other items = Rs. 76.50

Therefore, Ali receives a discount of Rs. 76.50 on the other items. This calculation demonstrates how a percentage discount can lead to substantial savings, especially when applied to larger purchase amounts. Understanding how to calculate these discounts is an essential skill for anyone looking to maximize their savings while shopping. By knowing the discount rate and the original price, consumers can quickly determine the actual savings they are receiving, helping them to make more cost-effective purchasing decisions.

Final Amount to Pay

Now that we have calculated the discounts on both fruit items and other items, we can determine the final amount Ali needs to pay. First, we need to calculate the price of each category of items after applying the discounts.

Price of fruits after discount = Total cost of fruits - Discount on fruits Price of fruits after discount = Rs. 380 - Rs. 76 Price of fruits after discount = Rs. 304

Next, we calculate the price of other items after the discount:

Price of other items after discount = Total cost of other items - Discount on other items Price of other items after discount = Rs. 510 - Rs. 76.50 Price of other items after discount = Rs. 433.50

Finally, to find the total amount Ali needs to pay, we add the discounted prices of the fruits and other items:

Total amount to pay = Price of fruits after discount + Price of other items after discount Total amount to pay = Rs. 304 + Rs. 433.50 Total amount to pay = Rs. 737.50

Therefore, Ali needs to pay Rs. 737.50 after applying the discounts. This comprehensive calculation illustrates the step-by-step process of applying percentage discounts and determining the final amount owed. Understanding these steps is vital for consumers to effectively manage their spending and take full advantage of available discounts, ultimately leading to better financial management and informed purchasing decisions.

Summary of Calculations

To recap, let's summarize the calculations we've performed to determine Ali's final expenses at the super store. This summary will provide a clear overview of the process and the key values involved.

  1. Total cost of fruits:
    • Bananas: Rs. 150
    • Apples: Rs. 230

  4. Total cost of other items:
    • Total: Rs. 510
  5. Discount on other items (15%):
    • Discount: 0.15 * Rs. 510 = Rs. 76.50
  6. Cost of other items after discount:
    • Price after discount: Rs. 510 - Rs. 76.50 = Rs. 433.50
  7. Total amount to pay:
    • Total: Rs. 304 + Rs. 433.50 = Rs. 737.50
