Question
Out of a city's population, 30% are not eligible to vote.
Of those who are eligible, 50% are females. If 2/5 of the eligible males and 3/10 of the eligible females vote, find the ratio of voting males to voting females.Solution
ATQ,
Let total population be 100n
Eligible voters = 0.7 × 100n = 70n
Eligible females = 0.50 × 70n = 35n
Eligible males = 70n – 35n = 35n
Males who voted = (2/5) × 35n = 14n
Females who voted = (3/10) × 35n = 10.5n
Required ratio = 14n : 10.5n = 4:3
