Processed food items incur a GST rate of 5%, while luxury cars attract a 28% rate. This serves as an instance of a percentage.
• Moreover, various stores frequently offer discounts during festive seasons or sales. For instance, a saree might incur a discount of 10%, while electronics may enjoy a 20% discount.
• In addition, students’ exam results in schools and colleges are commonly expressed in percentages, such that an individual who scores 75 out of 100 on an exam would be deemed to have scored 75%.

How to Calculate Percentage

To calculate a percentage, there are a few simple steps that one must follow. First, determine the total value of the quantity for which the percentage is desired. Then, determine the part or portion of the total value for which the percentage is calculated. Next, divide the part or portion value by the total value. Finally, multiply the resulting value by 100 to obtain the percentage value.

To calculate a percentage, you can use the formula:

Percentage = (Part/Total) x 100

For example, let’s say you want to find out what percentage of 200 is 60, you can use the same formula:

Percentage = (60/200) x 100

Percentage = 30%

Therefore, 60 is 30% of 200.

How to Calculate the Percentage of a Number

For example, if you want to find out 20% of 150, you can follow these steps:

1. Write down the number 150.
2. Convert the percentage value to a decimal by dividing it by 100. So here it would be, 20% is 0.2.
3. Multiply 150 by 0.2, which is 30.

Therefore, 20% of 150 is 30.

How to Calculate the Percentage of Marks

The formula for calculating the percentage is:

Percentage = (Obtained marks / Total marks) x 100

For example, if you scored 55 marks out of 100, then your percentage would be:

Percentage = (55 / 100) x 100

Percentage = 55%

Therefore, your percentage of marks would be 55%.
