Question

The value of 30% of Rs. 12 is

Answer 1

Hint: The given question is related to percentages. Express the given percentage as a fraction, then find the value of 30% of Rs.12.

Complete step-by-step answer:
Before proceeding with the problem, first, let’s understand the concept of percentages and fractions. Percent means per hundred. A fraction is defined as the amount of a part with respect to the whole value. For example: The ${{25}^{th}}$ part of the number 100 can be written as $\dfrac{25}{100}$ which can be further simplified to $\dfrac{1}{4}$ . The value written above is called the numerator and the value written below is called the denominator.
 Percentages can be expressed as fractions by writing the percentage in the numerator and 100 in the denominator. For example: 20% = $\dfrac{20}{100}$ , which can be written in its simplest form as $\dfrac{1}{5}$ .
Now, coming to the question, we are asked to find the value of 30% of Rs.12. We know, we can express 30% in fraction form as $\dfrac{30}{100}$ . So, 30% of Rs. 12 can be evaluated as $\dfrac{30}{100}\times 12$ .
$=\dfrac{360}{100}$
=Rs. 3.6
=Rs. 3 and 60 paise.
Hence, the value of 30% of Rs. 12 is Rs.6 and 60 paise.

Note: Percentages are a great way to compare two quantities. Also, the application of percentages is very vast in mathematics as well as day-to-day life. So, try to understand the concepts of percentages properly. Students generally make mistakes during calculations. Calculations should be done carefully as any mistake in calculation can lead to wrong answers.
