Question

What percent is 25 paise of 4 rupees?

Answer 1

Hint: First, we will convert the rupees in paise because we have to find the percentage of the amount which is in paise. The formula for finding the percentage of x of y is $\dfrac{{x \times 100}}{y}$. X and y must be in the same unit. To convert rupees into paise we have to multiply the term by 100.

Complete step by step answer:
We will convert rupees into paise. 1 rupee is equal to 100 paise.
So, $1\operatorname{Re} = 100paise$
Now, we will multiply 100 by 4.
$4Rs = 4 \times 100paise$
$4Rs = 400paise$
Now, we will find the percentage of 25 paise of 4 rupees using the percentage formula.
The formula is $\dfrac{{x \times 100}}{y}$
Here, x is equal to 25 paise and y is equal to 400 paise. Putting these values in the formula.
$ = \dfrac{{25 \times 100}}{{400}}$
$ = \dfrac{{2500}}{{400}}$
$ = 6.25\% $
The percent of 25 paise of 4 rupees is 6.25%.

Note:
To use the formula of percentage we should know that the value of numerator and denominator must be in the same unit. Rupees and paise are the units of measurement of money. It is not necessary to convert rupees to paise, we can also convert paise to rupees. To convert rupees to paise we multiply the term by 100 and to convert paise to rupees we will do the reverse of it we will divide the term by 100.
In this above case we converted rupees into paise as it makes the calculation easier. If we had converted paise into rupees the answer would come in points and calculation would become hard.
