Answer 1

Dear student
$$\begin{gathered} \mathrm{Let}\mathrm{total}\mathrm{pages}=\mathrm{x} \\ \mathrm{A}.\mathrm{T}.\mathrm{Q} \\ \frac{\mathrm{x}}{5}+40=\frac{7\mathrm{x}}{10} \\ \Rightarrow \frac{\mathrm{x}+200}{5}=\frac{7\mathrm{x}}{10} \\ \Rightarrow 10\mathrm{x}+2000=35\mathrm{x} \\ \Rightarrow -25\mathrm{x}=-2000 \\ \Rightarrow \mathrm{x}=80 \\ \mathrm{Sp},\mathrm{pages}\mathrm{left}=\frac{3}{10}\mathrm{of}\mathrm{pages} \\ =\frac{3}{10}\times 80 \\ =24\mathrm{pages} \end{gathered}$$
