The population of a town is 9000. It the number of females increases by 5% and the males by 7.5%, what will be the total population after increase. The number of females currently is 3000.

Solution

Number of females = 3000 and number of males = 6000

Females increases by 5% and the males by 7.5%

=> Total population after increase = $$[3000+(\frac{5}{100}\times3000)]+[6000+(\frac{7.5}{100}\times6000)]$$

= $$(3000+150)+(6000+450)$$

= $$9600$$

=> Ans - (A)
