    Solution

    Total number of employees in HR department = 150 × (1/3) = 50 Let total employees in Management and Sale be x and 3x respectively. And, total employees in Operation = 50 × (1 – 20/100) = 40 => 50 + x + 3x + 40 = 150 => 4x = 60 => x = 15 Number of male employees in Operation = 40×5/8 = 25 Required % = (25/50)×100 = 50%
