Answer 1

Dear student

$$\begin{gathered} \mathrm{Amount}\mathrm{salma}\mathrm{gave}\mathrm{to}\mathrm{shopkeeper}\mathrm{for}\mathrm{buying}\mathrm{onions}=\frac{21}{2}\times 18=\mathrm{Rs}189 \\ \mathrm{Amount}\mathrm{salma}\mathrm{gave}\mathrm{to}\mathrm{shopkeeper}\mathrm{for}\mathrm{buying}\mathrm{tomatoes}=\frac{13}{8}\times 16\frac{8}{11}=\frac{13}{8}\times \frac{184}{11}=\mathrm{Rs}\frac{299}{11} \\ \mathrm{So}\mathrm{money}\mathrm{that}\mathrm{she}\mathrm{gave}\mathrm{to}\mathrm{shopkeeper}=\mathrm{Rs}189+\mathrm{Rs}\frac{299}{11}=\mathrm{Rs}\left(189+\frac{299}{11}\right)=\mathrm{Rs}\left(\frac{2079+299}{11}\right)=\mathrm{Rs}\frac{2378}{11} \end{gathered}$$
