Question
‘N’ is the number of employees in an IT
company ‘ABC’. The average age of employees working in the company is 45 years. What will be the average age of these employees in next two years when 20 employees will get retire? Given that, retirement age is 60 years and N = 60.Solution
Total employees in the company = 60 Average age of employees = 45 Total age of employees = (60 × 45) = 270 In next two years, Total remaining employees = 60 – 20 = 40 Retirement age = 60 years Total age of 40 employees after 2 years = 2700 + (60 × 2) – (60 × 20) = 2700 + 120 – 1200 = 1620 ∴ Average age after two years = 1620/40 = 40.5 years
