Question

Find the number whose 8% is 40?​

Answer 1

Given: $x\times\frac{8}{100} =40$

We have to find the number.

• As we know that a percentage is a fraction of an amount is expressed as a particular number of hundredths of that amount.
• It is denoted by a symbol%.
• For example, $5 \%$ means$\frac{5}{100}$.
• By using the unitary method we are calculating the percentage of numbers.
• As we know fractions can be converted into percentages and vice-versa.
• And percentages are reversible.  
• For example, $50 \%of 60$is the same as$60 \% of 50$.

We are solving in the following way:

Let assume the number will be$x$.

$=>x\times\frac{8}{100} =40\\\\=>\frac{8x}{100} =40\\\\=>8x=40\times100\\\\=>8x=4000\\\\=>x=\frac{4000}{8} \\\\=>x=500$

Hence, the number will be$500$.
