To calculate 30% of 62 using the formula Percentage = (Percentage/100) x Total Amount, we can substitute the values as follows:
“`
Percentage = 30% = 30/100 = 0.3
Total Amount = 62
“`
Plugging these values into the formula, we get:
“`
30% of 62 = (30/100) x 62
= 0.3 x 62
= 18.6
“`
Therefore, 30% of 62 is 18.6.
This calculation demonstrates the practical application of the percentage formula in finding a specific portion of a given total amount. In this case, we were able to determine that 30% of 62 is equal to 18.6.

It is important to note that the calculation process remains the same regardless of the specific percentage or total amount involved. The formula provides a versatile framework for finding percentages in a wide range of scenarios.
Result: 30% of 62 is 18.6.
The result of our calculation, 18.6, represents the amount that is equivalent to 30% of 62. This value can be interpreted and used in various practical applications.
For example, if you have a total of 62 items and you want to find 30% of that quantity, the result, 18.6, tells you that you have 18.6 items that make up 30% of the total. This information can be useful for inventory management, product distribution, or any other situation where you need to determine a specific portion of a larger amount.
Another application of this result is in financial calculations. Suppose you have a loan with a principal amount of 62 and an interest rate of 30%. To calculate the interest you need to pay, you can use the formula Interest = Principal x (Interest Rate/100). Plugging in the values, we get:
“`
Interest = 62 x (30/100)
= 62 x 0.3
= 18.6
“`
Therefore, the interest you need to pay is 18.6. This demonstrates how the result of a percentage calculation can be used to determine specific values in financial transactions.
Understanding the significance of the result and its applications is essential for making informed decisions and solving problems effectively. By interpreting the result correctly, you can gain valuable insights and take appropriate actions based on the information obtained.
