A company has 1200 employees, with 45% working in
operations, 35% in sales, and the rest in HR. During an appraisal cycle, 20% of the operations employees, 15% of the sales employees, and 10% of the HR employees received promotions. How many employees did not receive a promotion?Solution
Employees in operation department = 45% of 1200 = 540 Employees in sales department = 35% of 1200 = 420 Employees % in HR department = 100% - 45% - 35% = 100% - 80% = 20% Employees in HR department = 20% of 1200 = 240 Number of employees who received promotion = 20% of 540 + 15% of 420 + 10% of 240 = 108+63+24 = 195 Number of employees who were not promoted = 1200 – 195 = 1005
