A person earns 1000rs
Q.1. A person earns Rs. 1000 in a day. He spends $\frac{2}{9}$ of it on transport and $\frac{3}{8}$ of it on food. How much money does he save in a day?

Answer 1

$$\begin{gathered} \mathrm{Hi}, \\ \mathrm{He}\mathrm{spent}\frac{2}{9}\mathrm{on}\mathrm{transport}\mathrm{and}\frac{3}{8}\mathrm{on}\mathrm{food}. \\ \mathrm{so}\mathrm{amount}\mathrm{spent}=\frac{2}{9}+\frac{3}{8}=\frac{16+27}{72}=\frac{43}{72}\mathrm{part} \\ \mathrm{so}\mathrm{amount}\mathrm{saved}=1-\frac{43}{72}=\frac{72-43}{72}=\frac{29}{72}\mathrm{part} \\ \mathrm{so}\mathrm{exact}\mathrm{amount}=\frac{29}{72}\times 1000=\mathrm{Rs}402.78 \end{gathered}$$
