Answer
Correct Answer: 378
Explanation
Introduction / Context:This is a percentage distribution problem. We are given total voters, the proportion of males, and the fraction of female votes a candidate secures. The goal is to compute the exact number of votes obtained by the candidate.
Given Data / Assumptions:
- Total voters = 1575.
- Male voters = 40% of 1575.
- Female voters = remaining voters.
- Candidate gets 40% of female voters.
Concept / Approach:Use successive percentages. First find males, then females, then compute 40% of the female count. Keep arithmetic exact to avoid rounding errors.
Step-by-Step Solution:
Males = 0.4 * 1575 = 630Females = 1575 - 630 = 945Candidate's votes = 0.4 * 945 = 378Verification / Alternative check:40% equals 2/5; 2/5 of 945 = 189 * 2 = 378. Same result, confirming accuracy.
Why Other Options Are Wrong:
- 945, 756, 630, 432: These correspond to totals or incorrect percentage applications. Only 378 correctly reflects 40% of the female voters.
Common Pitfalls:
- Taking 40% of the total instead of only the females.
- Computing females as 40% rather than 60% of the total.
Final Answer:378
