Answer 1

$$\begin{gathered} \mathrm{Monthly}\mathrm{earning}\mathrm{of}\mathrm{Sapna}=\mathrm{Rs}12000 \\ \mathrm{Expenditure}=\frac{7}{8}\mathrm{of}\mathrm{Rs}12000=\frac{7}{8}\times 12000=\frac{84000}{8}=\mathrm{Rs}10500 \\ \mathrm{Remaining}\mathrm{money}=12000-10500=\mathrm{Rs}1500 \\ \mathrm{So},\mathrm{monthly}\mathrm{saving}\mathrm{of}\mathrm{Sapna}=\mathrm{Rs}1500 \end{gathered}$$
