The tagged list price of a smartwatch is set at ₹4,000. During a seasonal sale, the store manager increases the promotional discount rate from 12% to 18%. What is the additional savings amount realized by a buyer?

Correct Answer: ₹240

To find the additional savings realized by the buyer, we can calculate the difference in discount amounts or calculate the difference in discount percentages directly.

Method 1: Step-by-Step Calculation of Discount Amounts

1. Calculate the initial discount at 12%:

$\text{Initial Discount}=12\%\text{of}₹\mathrm{4,000}$

$\text{Initial Discount}=\frac{12}{100}\times 4000=₹480$

2. Calculate the new discount at 18%:

$\text{New Discount}=18\%\text{of}₹\mathrm{4,000}$

$\text{New Discount}=\frac{18}{100}\times 4000=₹720$

3. Find the additional savings:

$\text{Additional Savings}=\text{New Discount}-\text{Initial Discount}$

$\text{Additional Savings}=₹720-₹480=₹240$

Method 2: Direct Difference in Percentage

1. Find the increase in discount percentage:

$\text{Increase in Discount Rate}=18\%-12\%=6\%$

2. Calculate 6% of the list price:

$\text{Additional Savings}=6\%\text{of}₹\mathrm{4,000}$

$\text{Additional Savings}=\frac{6}{100}\times 4000=₹240$

Therefore, the additional savings amount realized by the buyer is ₹240.
