    Correct option is C

    Given:
    ​Total population of the town = 10,000
    Male population increases by 5%
    Female population increases by 10%
    After the increase, the total population becomes 10,800. 
    Concept Used: 
    Total increased population = Total increased in male population + total increased in female population 
    total increased population = Male or female population×(1+Percent increase100)\text{Male or female population}\times \left( 1+\frac{\text{Percent increase}}{100}\right)  ​
