Answer 1

Question:

• 25% of certain sum of money is ruppes 5000 . Find the sum.

To Find:

• Sum = ?

Solution:

Let the required sum be x. Then,

25% of x = 5000

$\implies \dfrac{25}{100}\times x = 5000$

$\implies \dfrac{25x}{100} = 5000$

$\implies 25x = 5000\times100$

$\implies 25x = 500000$

$\implies x = \dfrac{500000}{25}$

$\implies x = 20000$

————————————————————

Hence, the required sum is 20000.

Extra Information:

• Percentage is a number or ratio that can be expressed as a fraction of 100.
• To convert a fraction into a percentage we multiply the fraction by 100.

Eg - $\dfrac{3}{4}\longrightarrow\Big(\dfrac{3}{4}\times100\Big)\%=75\%$

• To convert a percentage into fraction, divide it by 100 and convert that fraction in the simplest form.

Eg - $35\%\longrightarrow\dfrac{35}{100}\longrightarrow\dfrac{7}{20}$

• To convert a percentage as a ratio we have to first convert it as a fraction and then write it as a ratio.

Eg - $19\%\longrightarrow\dfrac{19}{100}\longrightarrow 19:100$

• To convert a ratio into percent we first have to convert it as a fraction and then multiply it by 100.

Eg - $1:2\rightarrow\dfrac{1}{2}\rightarrow\Big(\dfrac{1}{2}\times100\Big)\% \rightarrow 50\%$
