Waec Model Questions Vol1 2017 Government Question 25
Practice objective / multiple choice question 25 from the 2017 Waec Model Questions Vol1 Government examination.
A public agency evaluates employee performance using three criteria: Efficiency (E), Effectiveness (F) and Innovation (I). The overall score S is calculated as S = w₁·E + w₂·F + w₃·I, where the weights w₁, w₂, w₃ are non‑negative and sum to 1. For a particular employee the scores are E = 78, F = 85 and I = 92. The agency requires the overall score to be at least 84. Further constraints are: (i) the weight for Innovation must be at least twice the weight for Efficiency (w₃ ≥ 2w₁); (ii) the weight for Effectiveness must be at least 0.30 (w₂ ≥ 0.30); and (iii) each weight must be at least 0.10. What is the minimum possible weight for Innovation (w₃) that satisfies all the conditions?
