Mobile Phone Discount Calculation
This explanation details how to calculate the percentage discount given when a mobile phone is sold.
Key Information Provided
- Marked Price (MP): ₹16,800
- Selling Price (SP): ₹13,944
Step 1: Calculate the Discount Amount
The discount amount is the difference between the Marked Price and the Selling Price. We can calculate this using the formula:
$Discount Amount = Marked Price - Selling Price$
Substituting the values:
$Discount Amount = ₹16,800 - ₹13,944$
$Discount Amount = ₹2,856$
So, the actual amount of discount given was ₹2,856.
Step 2: Calculate the Discount Percentage
The percentage discount tells us how much the discount amount is relative to the original Marked Price. The formula is:
$Discount Percentage = (Discount Amount / Marked Price) * 100%$
Now, let's insert the values we have:
$Discount Percentage = (₹2,856 / ₹16,800) * 100%$
To calculate this:
$Discount Percentage = (2856 / 16800) * 100%$
$Discount Percentage = 0.17 * 100%$
$Discount Percentage = 17%$
Conclusion
The percentage discount given on the sale of the mobile phone was 17%.
