Effective Discount Calculation for Multiple Item Purchases

When dealing with item pricing and discounts, understanding how these discounts accumulate is crucial, especially when purchasing multiple items. In this article, we'll explore the effective discount calculation for a purchase scenario involving 5 items, each with specific pricing and discount conditions.

Scenario and Key Details

Rabia has an interesting purchase scenario:

First item marked price: Rs 200 Discount on first item: 25% Next four items marked price: Rs 200 each Discount on next four items: 50% Total purchase amount: 5 items

Step-by-Step Calculation

Step 1: Calculate the Cost Price (CP) for Each Item

Let's break down the calculation for each item:

Item 1:

Marked Price (MP) Rs 200 Discount on first item 25% Discount Amount 25% of Rs 200 Rs 44 CP of first item MP - Discount Amount Rs 200 - Rs 44 Rs 156

Items 2, 3, 4, and 5:

Marked Price (MP) for each of the next 4 items Rs 200 Discount on each of the next 4 items 50% Total Discount Amount for 4 items 50% of Rs 800 (4 x Rs 200) Rs 400 CP of each of the next 4 items MP - Discount Rs 200 - (50% of Rs 200) Rs 200 - Rs 100 Rs 100

Step 2: Calculate the Total Cost Price (CP)

CP of first item Rs 156 CP of each of the next 4 items Rs 100 Total CP Rs 156 4 x Rs 100 Rs 156 Rs 400 Rs 556

Step 3: Calculate the Total Discount Amount

Total SP (Selling Price) Total CP - Total Discount Total Marked Price (MP) for all 5 items 5 x Rs 200 Rs 1000 Total CP Rs 556 Total Discount Rs 1000 - Rs 556 Rs 444 Effective Discount Percentage (Total Discount / Total Marked Price) x 100 (Rs 444 / Rs 1000) x 100 44.4%

Alternate Method: Average Discount Calculation

We can also consider an alternate solution using the average discount method:

Discount percentage for:

1 item 25% for the first item 4 items 50% for each of the next 4 items

Total discount percentages (1 x 25%) (4 x 50%) 25% 200% 225%

Average Discount over 5 items Total discount percentages / Number of items 225% / 5 45%

Conclusion

The effective discount for Rabia's purchase of 5 items, given the specific discount conditions, is approximately 45%. This understanding can help in future purchasing scenarios, ensuring that discounts are optimally utilized.
