Answer 1

Dear student
$$\begin{gathered} \mathrm{Persons}\mathrm{required}\mathrm{to}\mathrm{build}\mathrm{house}\mathrm{in}8\mathrm{days}=3 \\ \mathrm{Persons}\mathrm{required}\mathrm{to}\mathrm{built}\mathrm{house}\mathrm{in}1\mathrm{day}=3\times 8 \\ \mathrm{Persons}\mathrm{required}\mathrm{to}\mathrm{built}\mathrm{house}\mathrm{in}6\mathrm{days}=\frac{3\times 8}{6}=4\mathrm{persons}. \end{gathered}$$
