      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
