Question
In a Village, 40% of the total population are females
and 60% of the males are literate people. If total number of literate males are 1440 and the ratio of the literate males and literate females is 4:3, respectively then find the percentage of the illiterate people out of the total population in the village.Solution
Let, the total population be 100x Number of females = 100x Γ 0.40 = 40x Number of males = 100x β 40x = 60x Literate male in the village = 60x Γ 0.60 = 36x Or, 36x = 1440 Or, x = 40 Total population = 4000 Literate females in the village = 1440 Γ (3/4) = 1080 Illiterate people in the village = 4000 β 1440 β 1080 = 1480 Percentage of illiterate people = (1480/4000) Γ 100 = 37%
