Question

Find the whole quantity if 40 % of it is 440 g?

Answer 1

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

          Given data:-  $40\%\ of\ x=440\ g.$

          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,

         $40\%\ of\ x=440\ g\\\\=>\frac{40}{100}\times x=440\\\\=> \frac{40x}{100}=440\\\\=>40x=440\times100\\\\=>40x=44000\\\\=>x=\frac{44000}{40} \\\\=>x=1100\ g.$

     Hence we will get the value is $1100\ g.$
