In this chapter, we will look at how we use the percentage as a measuring unit in our day to day life.

Before that, let's recall what we have studied in the previous chapter.
Percentage:

The term "per cent" means per hundred or for every hundred. This term has been derived from the Latin word "per centum".

We use the symbol ($$\%$$) for the term per cent.
Example:
20 per cent is written as 20 $$\%$$, and it means that "20 out of $$100$$."
