Question

x % of 120 = 80, then x = ?​

Answer 1

The given expression is $x$% of $120=80$

We have to find the value of x, we get

$x$ percentage of $120$ is equal to $80$

i.e. $\frac{x}{100} \times 120=80$

shifting the $120$ right side of denominator and $100$ to the numerator ,we get

$x=\frac{80\times 100}{120}$

one zero of numerator and denominator get cancelled remaining term

$x=\frac{800}{12}$

$x=66.67$

Therefore, the value of x is equal to $66.67$

Answer 2

• We have to evaluate the above expression by using the given data.

            Given data:- $x\%\ of\ 120=80.$

            To find:-Value of given expression=?

            Solution:-

• A percentage is a fraction of an amount expressed as a particular number of hundredths of that amount.

• It is denoted by %.

• We are using the unitary method to calculate the percentage of numbers.
• Fractions can be converted into percentages and vice-versa.

       Therefore,

         $x\%\ of\ 120=80\\\\=>\frac{x}{100} \times120=80\\\\=>\frac{120x}{100} =80\\\\=>120x=80\times100\\\\=>120x=8000\\\\=>x=\frac{8000}{120}\\\\=> x=\frac{200}{3}\\\\=>x=66.66 \%$

   Hence we will get $x\%\ of\ 120=80.$
