Dear student
$$\begin{gathered} \mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{comic}\mathrm{books}=643 \\ \mathrm{Number}\mathrm{of}\mathrm{comic}\mathrm{books}\mathrm{that}\mathrm{she}\mathrm{sold}=243 \\ \mathrm{Remaining}\mathrm{comic}\mathrm{books}=643-243=400 \\ \mathrm{She}\mathrm{packed}\mathrm{the}\mathrm{remaining}\mathrm{comic}\mathrm{books}\mathrm{into}6\mathrm{boxes} \\ \mathrm{So},\mathrm{No}.\mathrm{of}\mathrm{books}\mathrm{packed}\mathrm{in}1\mathrm{box}=\frac{\mathrm{Comic}\mathrm{books}\mathrm{left}}{\mathrm{No}.\mathrm{of}\mathrm{boxes}\mathrm{used}\mathrm{for}\mathrm{packing}}=\frac{400}{6}=66.6666=66\left(\mathrm{approx}\right) \\ \mathrm{No}.\mathrm{of}\mathrm{books}\mathrm{packed}=6\times 66=396 \\ \mathrm{No}.\mathrm{of}\mathrm{books}\mathrm{unpacked}=400-396=4 \end{gathered}$$
