The percentages of defective items for tables, chairs, and laptops are 20%, 40%, and 60% of their respective production levels.

    Solution

    ATQ,

    Production of chairs = (200/10) × 30 = 600 Number of non-defective chairs = 600 × 0.6 = 360 Production of laptops = (200/10) × 60 = 1200 Number of non-defective laptops =1200 × 0.4 = 480 Required difference = 480 – 360 = 120
