Correct Option: B (80%) Detailed Explanation: To determine the percentage of parents who enrolled their children in the boarding house after the fees were reduced, we need to analyze the context provided in "The Lekki Headmaster." While the specific details of the scenario are not provided here, we can infer that the reduction in fees likely made the boarding house more accessible and appealing to parents.

1. Understanding Percentage Calculation:
2. The percentage is calculated using the formula: [ \text{Percentage} = \left( \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \right) \times 100 ]
3. In this case, the "favorable outcomes" would be the number of parents who chose to enroll their children in the boarding house after the fee reduction, and the "total outcomes" would be the total number of parents surveyed or considered.
4. Interpreting the Options:
5. The options given are 60%, 80%, 70%, and 90%. To choose the correct answer, we need to consider the implications of each percentage:
   • 60%: This suggests that a little over half of the parents found the reduced fees appealing, which may not reflect a strong response to a fee reduction.
   • 70%: This indicates a significant majority but still leaves a considerable number of parents who did not enroll.
   • 80%: This suggests a very positive response to the fee reduction, indicating that a large majority of parents found the new fees acceptable and beneficial.
   • 90%: This implies almost universal acceptance, which may be unrealistic unless the fee reduction was substantial and the boarding house was already highly regarded.
6. Why Option B is Correct:
7. The choice of 80% reflects a strong positive response from parents, which is often the case when fees are reduced. It suggests that the reduction was significant enough to influence a large majority of parents to enroll their children. This aligns with common trends observed in educational settings where financial barriers are lowered, leading to increased enrollment.
8. Why Other Options are Weaker:
9. Option A (60%): This is too low to reflect a strong impact from the fee reduction. It suggests that many parents still found the fees prohibitive, which contradicts the expectation that a reduction would lead to higher enrollment.
10. Option C (70%): While this is a reasonable estimate, it does not capture the full extent of the positive impact that a fee reduction typically has. It suggests that a significant number of parents still opted out, which is less likely in a favorable scenario.
11. Option D (90%): This is likely an overestimation. While it indicates a very high level of satisfaction, it is rare for any program to achieve such a high enrollment rate unless there are exceptional circumstances. It may also imply that there are no barriers left, which is often not the case.

Common Pitfalls:

• Misunderstanding Percentages: Students often confuse the total number of parents with the number who enrolled, leading to incorrect calculations.
• Overgeneralizing: Assuming that all fee reductions will lead to very high enrollment rates without considering other factors (like the quality of the boarding house, location, etc.) can lead to incorrect conclusions.
• Ignoring Context: Not considering the specific context of the boarding house and the community can lead to misinterpretation of the data.

Revision Summary:

• The correct percentage of parents who enrolled their children after fee reduction is 80%.
• Use the percentage formula: (\text{Percentage} = \left( \frac{\text{Favorable outcomes}}{\text{Total outcomes}} \right) \times 100).
• Understand that a significant fee reduction typically leads to higher enrollment rates.
• Be cautious of overestimating or underestimating responses based on assumptions without data.
