Dear student

$$\begin{gathered} \mathrm{Total}\mathrm{monet}\mathrm{with}\mathrm{Ritu}=\mathrm{Rs}50 \\ \mathrm{She}\mathrm{bought}\mathrm{pen}\mathrm{for}\mathrm{Rs}\frac{17}{2} \\ \mathrm{She}\mathrm{bought}\mathrm{notebook}\mathrm{for}\mathrm{Rs}\frac{61}{4} \\ \mathrm{She}\mathrm{bought}\mathrm{gluestick}\mathrm{for}\frac{31}{4} \\ \mathrm{Amount}\mathrm{that}\mathrm{she}\mathrm{paid}=\frac{17}{2}+\frac{61}{4}+\frac{31}{4} \\ =\frac{17\times 2}{2\times 2}+\frac{61}{4}+\frac{31}{4} \\ =\frac{34}{4}+\frac{61}{4}+\frac{31}{4} \\ =\frac{34+61+31}{4} \\ =\frac{126}{4} \\ =\mathrm{Rs}\frac{63}{2} \\ \mathrm{Money}\mathrm{left}\mathrm{with}\mathrm{her}=\mathrm{Total}\mathrm{money}-\mathrm{Amount}\mathrm{that}\mathrm{she}\mathrm{paid} \\ =50-\frac{63}{2} \\ =\frac{100-63}{2} \\ =\mathrm{Rs}\frac{37}{2} \end{gathered}$$
