Question

Seventy percent (70%) of what number is 161?​

Answer 1

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

               Given data:- $70\% \times x=161.$

               To find:- The value of $x.$

               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.

• Percentages are reversible.  

           $\frac{70}{100} \times x=161\\=>\frac{7}{10} \times x=161\\=>7x=10\times161\\=>7x=1610\\=>x=\frac{1610}{7}\\=>x=230.$

          Hence we will get $70\%\ of\ 230\ is\ 161.$
