Example of How to find out Percentages

 

Let’s watch this video for more insight:

so How do we calculate a percentage

To do this we will take a real life example:

 

First Example : What percentage of my spending over my initial budget?

I have 50 euros and I decided to spend 17 euros on the purchase of vegetables.

What percentage is this expenditure over my initial budget?

Solution: Nothing complicated,

just divide 17 euros by my initial budget is:

17/50 = 0.34

Then multiply the result by 100 to get a percentage:

0.34 X 100 = 34%


We have therefore used 34% of our total budget.

 

Second Example: How to find the percentage of my discount?

I buy a car to 9,000 euros after negotiations with the seller, I am happy because the original price was 11,000 euros.

But what is the percentage of my discount?

 

Solution:

We had therefore  a reduction of:

11000 – 9000 = 2000 euros.

2000/11000 = 0.18 X 100 = 18%

So I got 18% discount

You will then be able  calculate a percentage without worries!

Third Example:  How to calculate a rebate by a trader?

A merchant gives you a 20% discount on a product whose price is 400 €. How do I know what price I will finally pay?

Solution:

For this we assume a 20% discount means that the merchant gives you a € 20 discount for every € 100, in total € 80 discount for a 100 € (400/100 × 20) or (400 × 0.2). To calculate the price you ultimately pay is multiplied by € 400 0.8.

Fourth Example: how to calculate the interest that my savings will make in one year?

Suppose you put € 1,000 at a rate of 2.5% on a savings account. How much interest will this investment earn you 1 year?

Solution :

An annual rate of 2.5% means that you will receive € 2.5 to € 100 per year invested. If you invest € 1000 this investment will bring logically 10 × 2.5 € or 25 €.
