UP Police Constable Exam Model Paper 5

Given
Distance between two places $=25\mathit{k}\mathit{m}$
Scale$=1:50000$
Concept used:
$1\mathit{k}\mathit{m}=1000\mathit{m}$
$1\mathit{m}=100\mathit{c}\mathit{m}$
$1\mathit{k}\mathit{m}=100000\mathit{c}\mathit{m}$
Map scale: It is a ratio of the distance on the map to the corresponding distance on the ground
Calculation:
Let the distance between two places on the map be $\mathit{x}\mathit{c}\mathit{m}$
$\Rightarrow \frac{\mathit{x}}{25}=\frac{1}{50000}$
$\Rightarrow \frac{\mathit{x}}{2500000}=\frac{1}{50000}$ $\cdots -\left(25\mathit{k}\mathit{m}=2500000\mathit{c}\mathit{m}\right)$
$\Rightarrow \mathit{x}=\frac{250}{5}$
$\Rightarrow \mathit{x}=50\mathit{c}\mathit{m}$
$\therefore$ The distance between the two places on the map is $50\mathit{c}\mathit{m}$
