1. 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

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%
