Answer 1

Dear Student,

$$\begin{gathered} \mathrm{Let}\mathrm{the}\mathrm{monthly}\mathrm{salary}=\mathrm{Rs}\mathrm{x} \\ \mathrm{Percentage}\mathrm{of}\mathrm{salarycentage}\mathrm{of}\mathrm{salary}\mathrm{saved}=\left(100-83\right)\%=17\% \\ \mathrm{Now},\mathrm{accpording}\mathrm{to}\mathrm{question}: \\ 17\%\mathrm{of}\mathrm{Rs}\mathrm{x}=\mathrm{Rs}1870 \\ \Rightarrow \frac{17}{100}\times \mathrm{x}=1870 \\ \Rightarrow \mathrm{x}=11000 \\ \mathrm{So},\mathrm{monthly}\mathrm{salary}=\mathrm{Rs}11000 \end{gathered}$$
