Question

(i) Find $16\frac{2}{3}\%$ of $30$.

(ii) Find $15\%$ of $Rs.140$

Answer 1

(i)

$\begin{array}{cc}16\frac{2}{3}\%\text{of}30& =16\frac{2}{3}\times \frac{1}{100}\times 30\\ & =\frac{50}{3}\times \frac{3}{10}\\ & =5\end{array}$

(ii)

$\begin{array}{cc}15\%\text{of}Rs.140& =\frac{15}{100}\times 140\\ & =\frac{3}{2}\times 14\\ & =3\times 7\\ & =Rs.21\end{array}$
