Question
In a certain village, 10% of the people can't vote. Out of
the rest, 60% are females. During an election, 1/2 of eligible males and 1/5 of eligible females voted. What is the ratio of male to female voters?Solution
ATQ,
Let population be 100n
Eligible voters = 0.9 × 100n = 90n
Eligible females = 0.60 × 90n = 54n
Eligible males = 90n – 54n = 36n
Males who voted = (1/2) × 36n = 18n
Females who voted = (1/5) × 54n = 10.8n
Required ratio = 18n : 10.8n = 5:3
