    Answer:

    30% are children

    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

    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%
