Total number of males in the police station = 10
Total number of females in the police station = 5
So, Total number of officers in the police station = Number of males in police station + Number of females in the police station
= 10+5
= 15
So, total number of officers in the police station = 15
Now, we have to find the ratio of number of male officers to the total number of officers.
So, Ratio = Number of male officers
Total number of officers
=

=

=

= 2:3
So, the ratio of male officers to the total number of officers is 2:3.
