In a remote village in Idukki district 20%
of the adults are illiterate, while 85% of
the children are literate. If the ratio of
the adults to that of the children is 2 : 3,
then what percentage of population is
illiterate ?​

Answer 1

LET POPULATION 100

illterate adult 40*40/100=16

literate adult 24

literate chldren 51

so total literate is 75option not there. its 70%

let total poppulation = 100

adults = 60

children= 40

illiterate adults = 40% of 60 = 24

literate adults= 60-24= 36

literate children = 85% of 40 = 34

there fore total literate = 36+34 = 70 ans
