The sales They are the perfect time to buy those whims you have had your eye on during Christmas and get them at a much cheaper price. However, it is very important calculate discount for items Y know the final price to know if the percentage of discount that stores and businesses promise is really being applied. Although discounts are usually marked on the labels of the items along with the discounted price, with the hustle and bustle of the sales it is easy to fall into the traps of some rogues. Have you ever stopped to calculate if the discount is real? So today we are going to show you how to calculate the discount percentage and know if they are cheating you on sales.
How to calculate a discount
For calculate discount percentage There is only a very simple operation to do, but this can be cumbersome or complicated for some people. Fortunately, this process is greatly simplified if we have the mobile phone calculator that we all carry in our pocket today. So take note of this trick to calculate a discount quickly and easily. To do this, you must know the original price of the discounted item that has to be visible on the label and the discount percentage that is applied.
First you have to divide the discount percentage by 100 to get a decimal number. For example, to calculate the discount for an item that has a 15% discount you will have to divide 15 by 100 (15/100 = 0.15)
The next step will be to multiply this decimal number by the original price to get the money that the discount supposes. If the original price of the garment is 60 euros and the discount percentage is 15%, the operation will be as follows: 60 x 0.15 = 9. These 9 euros will be the money that we save, that is, the money that we discounted on the sale.
Finally, we must deduct this amount from the original price, with the following subtraction: 60-9 = 51 euros.
The mathematical trick to calculate a discount
In addition to the previous operation to calculate a discount, the mathematician from the University Miguel Hernández Santi Garcia Cremades, released another trick to calculate a sale discount in the program La Roca de La Sexta. To use this method to calculate discount percentage And do not be deceived in sales, you must follow the following steps:
First of all, we must divide the final price, that is, the reduced price, by the original price. For example, if we have an item that cost 34.99 and is now 27.99, we must do the following count: 27.99 / 34.99 = 0.79994.
The next step will be to subtract 1 from the resulting figure: 0.7999 – 1 = -0.20.
If we put the result in positive, this figure will give us the discount percentage. In this case it will be 20%.
