Difficulty: Easy
Correct Answer: 600
Explanation:
Introduction / Context: Majority in a two-candidate election equals the difference between the winner’s and loser’s shares of the total votes. When percentages are given, the majority is simply (winner% − loser%) of total. Use that to solve for the total number of votes.
Given Data / Assumptions:
Concept / Approach: Majority = (62% − 38%) of V = 24% of V. Therefore, 0.24V = 144. Solving yields V. This avoids separately computing each candidate’s votes first.
Step-by-Step Solution:
Let total votes be V.Majority share = (0.62 − 0.38) * V = 0.24V.Set 0.24V = 144 ⇒ V = 144 / 0.24 = 600.Verification / Alternative check: Winner votes = 0.62*600 = 372; loser votes = 228; difference = 372 − 228 = 144. Correct.
Why Other Options Are Wrong: 800, 925, 1200 produce majority values of 192, 222, and 288 respectively, not 144.
Common Pitfalls: Misreading 62% as the majority itself, or forgetting that majority is a percentage of total, not of the winner’s votes.
