Answer
Correct option: D.
none of these.
None of these $0.8\ cm$ represent the map $= 8.8\ km$
$1\ cm$ will represent on the map $=\frac{8.8}{0.8}\text{km}$
$\therefore 80.5\ cm$ will represent on the map
$=\frac{8.8\times80.5}{0.8}=\frac{88\times805\times10}{10\times8\times10}$
$=\frac{8855}{10}=885.5\text{km}$
$1\ cm$ will represent on the map $=\frac{8.8}{0.8}\text{km}$
$\therefore 80.5\ cm$ will represent on the map
$=\frac{8.8\times80.5}{0.8}=\frac{88\times805\times10}{10\times8\times10}$
$=\frac{8855}{10}=885.5\text{km}$
