Calculate Original Amount Now! →Understanding the Basics
Before diving into the calculations, let's clarify the core concepts. A percentage is simply a way of expressing a number as a fraction of 100. When you know a percentage and a related value, you can determine the original amount that the percentage is based on. There are three basic percentage problems:
- Finding a percentage of a number (e.g., What is 15% of 200?).
- Determining what percentage one number is of another (e.g., 30 is what percent of 150?).
- Calculating the original amount when you know a percentage of it (e.g., If 20% of a number is 50, what is the original number?).
This article focuses on solving the third type of problem: how to find actual amount from percentage.
The Formula for Finding the Actual Amount
The basic percentage formula is:
Percentage × Original Amount = Actual Amount
When finding the original amount, we rearrange the formula to solve for the "Original Amount":
Original Amount = Actual Amount / Percentage
Key Considerations:
- Convert the Percentage to a Decimal: Before using the formula, always convert the percentage to its decimal form by dividing it by 100. For example, 25% becomes 0.25.
- Identify the Actual Amount: This is the value you know, which represents a specific percentage of the original amount.
Step-by-Step Examples
Let's illustrate with examples:
Example 1: Finding the Original Price After a Discount
A store offers a 20% discount on a shirt, and you pay $40. What was the original price of the shirt?
- Convert the Percentage: 20% = 0.20
- Recognize that $40 represents 80% of the original price (100% - 20% = 80%).
- Identify the percentage we need to work with: 80% = 0.80
- Apply the Formula: Original Price = $40 / 0.80 = $50
Therefore, the original price of the shirt was $50.
Example 2: Determining the Original Score on a Test
You answered 80 questions correctly on a test, achieving a score of 64%. How many questions were on the test in total?
- Convert the Percentage: 64% = 0.64
- Apply the Formula: Total Questions = 80 / 0.64 = 125
Therefore, there were 125 questions on the test.
Example 3: Calculating the Initial Investment
An investment grew by 10% and is now worth $1100. What was the original investment?
- Convert the Percentage: 10% = 0.10
- Recognize that $1100 represents 110% of the original investment (100% + 10% = 110%).
- Identify the percentage we need to work with: 110% = 1.10
- Apply the Formula: Original Investment = $1100 / 1.10 = $1000
Therefore, the original investment was $1000.
