Calculate Supervisor's Salary
The problem asks for the supervisor's salary given the average salary of workers before and after the supervisor is included.
Initial Information
- Number of workers = 40
- Average salary of 40 workers = Rs. 24,000
- Number of people after adding supervisor = 40 + 1 = 41
- New average salary (including supervisor) = Rs. 24,500
Calculating Total Salaries
First, calculate the total salary of the 40 workers:
Total Salary (Workers) = Number of Workers $ \times $ Average Salary of Workers
Total Salary (Workers) = $ 40 \times 24,000 = 960,000 $
Next, calculate the total salary of the 41 people (40 workers + 1 supervisor):
Total Salary (41 People) = Number of People $ \times $ New Average Salary
Total Salary (41 People) = $ 41 \times 24,500 = 1,004,500 $
Determining Supervisor's Salary
The supervisor's salary is the difference between the total salary of 41 people and the total salary of the 40 workers.
Supervisor's Salary = Total Salary (41 People) - Total Salary (Workers)
Supervisor's Salary = $ 1,004,500 - 960,000 $
Supervisor's Salary = $ 44,500 $
Conclusion
The supervisor's salary is Rs. 44,500.
