A) 24
b) 28
C) 34
D) 32​

Answer 1

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

               Given data:- $75\%\times x=18.$

               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,

          $75\%\times x=18\\=>\frac{75}{100}\times x=18\\=>\frac{75x}{100}=18\\=>75x=18\times100\\=>75x=1800\\=>x=\frac{1800}{75}\\=>x=24$

       Hence we will get the value is $x=24.$

Answer 2

Given: $75\%\ of\ x\ is\ 18$

We have to find the missing number.

We are solving in the following way:

Let assume the missing number will be$x$.

Then, from the given statement we can write:

$75\%\ of\ x\ is\ 18$

Solving the above equation further we get,

$=>\frac{75}{100} \times x=18\\\\=>\frac{75x}{100} =18\\\\=>75x=18\times 100\\=>75x=1800\\\\=>x=\frac{1800}{75} \\\\=>x=24$

Hence, $75\%\ of\ 24\ is\ 18$
