Question
Find the total number of participants in the Quiz
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%.
