Question
In a town, 25% of the residents are underage and hence not
allowed to vote. Among the eligible voters, 40% are women. If 1/4 of the eligible women and 2/5 of the eligible men participate in the voting, what is the ratio of men to women who voted?Solution
ATQ,
Let total number of residents be 100n
Eligible voters = 0.75 Ă— 100n = 75n
Eligible women = 0.40 Ă— 75n = 30n
Eligible men = 75n – 30n = 45n
Men who voted = (2/5) Ă— 45n = 18n
Women who voted = (1/4) Ă— 30n = 7.5n
Required ratio = 18n : 7.5n = 12:5
