Question
In an election between two candidates 'P' and 'Q', 'P'
got 55% of the votes and won by 4,400 votes. Find the number of votes received by 'Q'.Solution
ATQ, Let the total votes be 100n. Votes received by 'P' = 0.55 Γ 100n = 55n. Votes received by 'Q' = 100n β 55n = 45n. So, 55n β 45n = 4,400. Or, 10n = 4,400. Or, n = 440. Therefore, number of votes received by 'Q' = 45 Γ 440 = 19,800.
