One rupee interest means 12%. Each month, one rupee in interest is calculated on the principal amount. For instance, if a person loans Rs 100 at Rs 1 interest, he will need to pay Rs 1 in interest each month. Therefore, he must pay 12 rupees a year. A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics.

If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

### Formula to calculate Percentage

We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.

The formula for percentages: (Value/Total value) x 100

How percentage of a number can be calculated?

We must use a different formula, such as P% of Number = X, where X represents the required percentage, to determine the percentage of a number.

If we don't use the percent sign, we must write the equation above as P/100 x Number = X.

Hence, Re 1 interest Rs 100 indicates that the interest rate is 12%.
