Question

The cost of 2 1/2 metres of cloth is Rs 78 3/4. Find the cost of cloth per metre ?

Answer 1

$$\begin{gathered} \mathrm{cost}\mathrm{of}2\frac{1}{2}\mathrm{metres}\mathrm{of}\mathrm{cloth}=\mathrm{Rs}.78\frac{3}{4} \\ \mathrm{So}\mathrm{cost}\mathrm{of}1\mathrm{metre}\mathrm{of}\mathrm{cloth}=\frac{78{\displaystyle \frac{3}{4}}}{2{\displaystyle \frac{1}{2}}}=\frac{{\displaystyle \frac{315}{4}}}{{\displaystyle \frac{5}{2}}}=\frac{315}{4}\times \frac{2}{5}=\frac{63}{2}=\mathrm{Rs}.31\frac{1}{2} \end{gathered}$$
