One of the candidates secured 9975 votes, which accounted for 75% of the total valid votes. Determine the total number of eligible voters.Solution
ATQ,
Let number of eligible voters be β100yβ Number of eligible voters who cast their votes = 0.80 Γ 100y = β80yβ Total number of valid votes = 0.95 Γ 80y = β76yβ ATQ, 76y Γ 0.75 = 9975 Or, y = 175 Therefore, total number of eligible voters = 100y = (100 Γ 175) = 17500
