Answer 1

$$\begin{gathered} \mathrm{Let}\mathrm{the}\mathrm{required}\mathrm{number}=\mathrm{x} \\ \mathrm{Now}\mathrm{its}\mathrm{half}=\frac{\mathrm{x}}{2} \\ \mathrm{Now},\mathrm{according}\mathrm{to}\mathrm{question}: \\ \mathrm{x}+\frac{\mathrm{x}}{2}=36 \\ \Rightarrow \frac{3\mathrm{x}}{2}=36 \\ \Rightarrow 3\mathrm{x}=72 \\ \Rightarrow \mathrm{x}=\frac{72}{3}=24 \\ \mathrm{So},\mathrm{the}\mathrm{required}\mathrm{number}=24 \end{gathered}$$
