Introduction
Mathematics is an essential subject that we learn from the early stages of our education. Throughout the years, we come across many mathematical concepts and formulas that help us solve problems in our daily lives. One such concept is the 90 percent of 20, which we will discuss in this article.
What is 90 Percent of 20?
90 percent of 20 is a mathematical concept that helps us calculate a certain percentage of a given value. In simpler terms, it implies that out of 20, 90 percent or 18 is the value we are looking for.
Why is it Important?
Understanding 90 percent of 20 is crucial in various fields such as finance, business, and even in our daily lives. For instance, when we calculate discounts or taxes, we use percentages. Similarly, in business, we use percentages to analyze trends and make informed decisions.
How to Calculate 90 Percent of 20?
To calculate 90 percent of 20, we use a simple formula:
90/100 x 20 = 18
This implies that 90 percent of 20 is 18.
Applications of 90 Percent of 20
Now that we know what 90 percent of 20 is and how to calculate it let’s look at some real-life applications:
Discounts
When we go shopping, we often come across discounts on various products. For example, a store may offer a 90 percent discount on a product worth $20. In such a scenario, we can calculate the discounted price using 90 percent of 20:
90/100 x 20 = 18
This implies that the discounted price of the product is $2.
Taxes
Similarly, when we pay taxes, we use percentages to calculate the amount. For instance, if we have to pay a tax of 90 percent on a product worth $20, we can calculate the tax amount using 90 percent of 20:
90/100 x 20 = 18
This implies that the tax amount we have to pay is $18.
Business
Businesses use percentages to analyze trends and make informed decisions. For example, a company may analyze the sales figures and calculate the percentage increase or decrease in sales. Similarly, they may calculate the percentage profit or loss on their investments.
Conclusion
90 percent of 20 is a simple yet essential mathematical concept that we use in our daily lives. From calculating discounts to analyzing trends, this concept has numerous applications. Understanding this concept can help us make informed decisions and solve problems efficiently.
