Question
In a mayoral election, candidate P got 75% of the total
votes, winning over candidate Q by 9,600 votes. What is the number of votes secured by candidate Q?Solution
ATQ,
Let total votes = 100n
Votes for P = 75n
Votes for Q = 100n - 75n = 25n
75n - 25n = 9,600
⇒ 50n = 9,600
⇒ n = 192
Votes received by Q = 25 × 192 = 4,800
