Question

20 percentage of a number is 400 then find that number

Answer 1

• As per the data given in the question, we have to determine the required number.

        Given data:- $20\%$ of a number is $400.$

         Solution:-

• A percentage is a fraction of an amount expressed as a particular number of hundredths of that amount.
• It is denoted by %. $1\%$means $\frac{1}{100}.$
• We are using the unitary method to calculate the percentage of numbers.
• Fractions can be converted into percentages and vice-versa.
• Percentages are reversible. For example, $30\%$ of $40$ is the same as $40\%$ of $30.$

       According to the question,

       $\Rightarrow \frac{20}{100}\timesx=400\\\Rightarrow \frac{100\times400}{20}\\\Rightarrow x=2000.$

     Hence, the value will be $2000.$

Answer 2

Answer:

$2000$

Step-by-step explanation:

• It is given that the $20$% of a number is $400$.
• Let, the number be x.
• According to given condition, the equation becomes
• $20$% of x = $400$
• ∴ $\frac{20}{100} *x=400$

     ∴ $x = \frac{400*100}{20}$

     ∴ $x=20*100$

     ∴ $x = 2000$

• ∴ The number is $2000$.
