Question
In a village, number of male, female and children are in
the ratio of 3:5:7. If 90% of the males are literate, 80% of females are literate and 40% of children are illiterate, find the % of number of illiterate persons in the village.Solution
Let us assume that no. of Male, Female and Children be 300, 500 and 700 respectively. Total no. of persons = 1500 No. of literate males = 90% of 300 = 270 No. of illiterate males = 300 -270 = 30 No. of literate females = 80% of 500 = 400 No. of illiterate females = 500 - 400 = 100 No. of illiterate children = 40% of 700 = 280 No. of literate children = 700 -280 = 420 Total no. of illiterate persons = 30 + 100 + 280= 410 So % of illiterate = 410/1500X100 = 27.33%
