    Solution

    ATQ,

    Let total population be 100n

    Eligible voters = 0.7 Ă— 100n = 70n

    Eligible females = 0.50 Ă— 70n = 35n

    Eligible males = 70n – 35n = 35n

    Males who voted = (2/5) Ă— 35n = 14n

    Females who voted = (3/10) Ă— 35n = 10.5n

    Required ratio = 14n : 10.5n = 4:3
