Question

Average age of employees working in a department is 30 years. In the next year, ten workers will retire. What will be the average age in the next year?

Answer 1

Answer:

Retirement age is 60 years.

II. There are 50 employees in the department.

Average age of 50 employees = 30 years.

Total age of 50 employees = (50 \times 30) years = 1500 years.=(50×30)years=1500years.

Number of employees next year = 40.

Total age of 40 employees next year (1500 + 40 - 60 \times 10) = 940.(1500+40−60×10)=940.

Average age next year = \dfrac{940}{40} years = 23 \dfrac{1}{2} years.=

40

940

years=23

2

1

years.

Thus, I and II together give the answer. So, correct answer is (E).
