Question

Find the cost of $3\frac{1}{3}$ m of cloth at Rs $121\frac{1}{2}$ per metre.

Answer 1

$\begin{array}{l}\text{Cost of 1 m cloth = Rs 121}\frac{1}{2}\\ \text{Cost of 3}\frac{1}{3}\text{m cloth = 121}\frac{1}{2}\times 3\frac{1}{3}\\ \text{=}\frac{{\sout{243}}^{81}}{\sout{2}}\times \frac{\sout{1}{\sout{0}}^5}{\sout{3}}\\ \text{=Rs 405}\\ \end{array}$
