Answer 1

$$\begin{gathered} \mathrm{Monthly}\mathrm{income}\mathrm{of}\mathrm{Mrs}\mathrm{Shah}=\mathrm{Rs}30,000 \\ \mathrm{She}\mathrm{spends}25\%\mathrm{of}\mathrm{monthly}\mathrm{income}\mathrm{on}\mathrm{grocery}\mathrm{items}. \\ \mathrm{Money}\mathrm{spent}\mathrm{on}\mathrm{grocery}\mathrm{items}=25\%\mathrm{of}30,000 \\ =\frac{25}{100}\times 30000=\mathrm{Rs}7500 \\ \mathrm{She}\mathrm{spends}20\%\mathrm{of}\mathrm{monthly}\mathrm{income}\mathrm{on}\mathrm{house}\mathrm{rent}. \\ \mathrm{Money}\mathrm{given}\mathrm{as}\mathrm{house}\mathrm{rent}=20\%\mathrm{of}30,000 \\ =\frac{20}{100}\times 30000=\mathrm{Rs}6000 \\ \mathrm{Money}\mathrm{spent}\mathrm{on}\mathrm{both}\mathrm{grocery}\mathrm{items}\mathrm{and}\mathrm{house}\mathrm{rent}=7500+6000=\mathrm{Rs}13,500 \\ \mathrm{Hence},\mathrm{Mrs}.\mathrm{Shah}\mathrm{spends}\mathrm{Rs}13,500\mathrm{on}\mathrm{both}\mathrm{grocery}\mathrm{items}\mathrm{and}\mathrm{house}\mathrm{rent}. \end{gathered}$$
