let the %of a town be 100 .

so 300% are female and 40% are male

by adding both we get 70%

% of children = 100%-70%

30% is the correct answer

Answer 2

Step-by-step explanation:

let ,the total percent of people in city be 100%

percent of females= 30%

percent of males = 40%

so,per cent of children is-

total percent of people in city- percent of females + percent of males

100% - 30% +40%

100% -70%

30%

so,per cent of children in the city is 30%
