The correct Answer is:
To solve the problem step by step, we will follow the reasoning provided in the video transcript. ### Step-by-Step Solution: 1. **Let the total votes be \( x \)**: - We denote the total number of votes polled in the election as \( x \). **Hint**: Define the total votes as a variable to simplify calculations. 2. **Votes secured by the winner**: - The winner secured 68% of the total votes, which can be expressed as: \[ \text{Votes secured by winner} = \frac{68}{100} \times x = 0.68x \] **Hint**: Convert the percentage into a decimal to calculate the votes. 3. **Votes secured by the loser**: - The loser secured the remaining votes, which is 32% of the total votes: \[ \text{Votes secured by loser} = \frac{32}{100} \times x = 0.32x \] **Hint**: Remember that the sum of the percentages of votes secured by both candidates should equal 100%. 4. **Set up the equation for the difference in votes**: - According to the problem, the difference between the votes secured by the winner and the loser is 23,040. We can write this as: \[ 0.68x - 0.32x = 23,040 \] **Hint**: Use the information about the difference in votes to form an equation. 5. **Simplify the equation**: - Simplifying the left side gives: \[ 0.36x = 23,040 \] **Hint**: Combine like terms to simplify the equation. 6. **Solve for \( x \)**: - To find \( x \), divide both sides by 0.36: \[ x = \frac{23,040}{0.36} \] - Calculating this gives: \[ x = 64,000 \] **Hint**: When dividing, ensure you maintain the decimal places correctly. 7. **Calculate the votes secured by the winner**: - Now that we have the total votes, we can find the votes secured by the winner: \[ \text{Votes secured by winner} = 0.68 \times 64,000 \] - This calculation results in: \[ \text{Votes secured by winner} = 43,520 \] **Hint**: Multiply the percentage of votes by the total to find the winner's votes. ### Final Answer: The votes secured by the winner is **43,520**.
