Answer 1

$$\begin{gathered} \mathrm{Earning}\mathrm{of}\mathrm{man}=\mathrm{Rs}7200 \\ \mathrm{Money}\mathrm{spent}\mathrm{on}\mathrm{food}=\frac{3}{10}\times 7200=\mathrm{Rs}2160 \\ \mathrm{Money}\mathrm{spent}\mathrm{on}\mathrm{house}\mathrm{rent}=\frac{1}{4}\times 7200=\mathrm{Rs}1800 \\ \mathrm{Money}\mathrm{spent}\mathrm{on}\mathrm{insurance}=\frac{1}{10}\times 7200=\mathrm{Rs}720 \\ \mathrm{Money}\mathrm{spent}\mathrm{on}\mathrm{holidays}=\frac{2}{25}\times 7200=\mathrm{Rs}576 \\ \mathrm{Total}\mathrm{expenditutre}=2160+1800+720+576=\mathrm{Rs}5256 \\ \mathrm{Savings}=7200-5256=\mathrm{Rs}1944 \end{gathered}$$
