category over the five years and calculate its percentage contribution to the total participants across all categories over these five years. A school organizes competitions in five categories: Debate, Quiz, Music, Dance, and Art. The table below shows the number of participants in each category over five years.Solution
Total participants in the Quiz category: Quiz total = 150 + 170 + 180 + 200 + 220 = 920. Total participants across all categories: Debate total = 120 + 140 + 160 + 180 + 200 = 800. Quiz total = 920. Music total = 200 + 220 + 240 + 260 + 300 = 1220. Dance total = 180 + 200 + 210 + 250 + 280 = 1120. Art total = 100 + 120 + 150 + 180 + 200 = 750. Grand total = 800 + 920 + 1220 + 1120 + 750 = 4810. Percentage contribution of Quiz: Percentage = (Quiz total / Grand total) × 100 = (920 / 4810) × 100 ≈ 19.12%. Correct answer: a) 920, 19.12%.
