Question

Calculate the value of the given: 30% of $₹\,300$.

Answer 1

Hint: Over here we have to find the value of a certain percentage of a sum of money.
The formula for calculating percentage is given as:
$x\% $ of a quantity $ = \dfrac{x}{{100}} \times quantity$

Complete step by step answer:
Now, we need to find the value of 30% of $₹\,300$, which means we need to use the concept of calculation of the percentage values. A certain Percentage means its value out of 100.
Now, since here the total amount given is $₹\,300$, so when we calculate 30% of $₹\,300$, it will give us what is the value of 30% of this amount.
So we know, that x% of a quantity say, n is given as:
\[
  x\% \:of \:n \\
   = \dfrac{x}{{100}} \times n \\
\]
So, applying the same to 30% of $₹\,300$ we will get
$
  30\% \:of \:300 \\
   = \dfrac{{30}}{{100}} \times 300 \\
   = 30 \times 3 \\
   = 90 \\
$
Which is $₹\,90$.
Therefore, the value of 30% of $₹\,300$ is $₹\,90$.

Note: Percentage is used widely in marks distribution. For example if we say that the child has scored 76% it means the child has scored 76 marks out of 100 marks. We need to be careful with the quantity whose percentage we are calculating. Percentage itself does not have any unit, it takes the unit of the quantity whose percentage we are calculating. For instance, if we are calculating the percentage of marks then the units will be marks, if money then the unit will be of the respective currency.
