To find the valid votes of the losing candidate in the election, we will follow these steps:
Calculate the number of invalid votes.
The total number of votes polled is 15,200 and 15% of these votes were invalid.
Therefore, the number of invalid votes is calculated as:
\(= \left(\frac{15}{100}\right) \times 15200 = 2280\)
Determine the number of valid votes.
Valid votes = Total votes polled - Invalid votes
\(= 15200 - 2280 = 12920\)
Find the number of valid votes received by the winning candidate.
The winning candidate received 55% of the total valid votes. Therefore,
\(= \left(\frac{55}{100}\right) \times 12920 = 7106\)
Calculate the number of valid votes received by the losing candidate.
Since the sum of the votes for both candidates must equal the total valid votes, we calculate the votes for the loser as:
Valid votes for loser = Total valid votes - Valid votes for winner
\(= 12920 - 7106 = 5814\)
Thus, the number of valid votes received by the losing candidate is 5814.
Option 5814 is the correct choice.
