The average salary of employees of a factory is ₹15,000. The average salary of 250 of the employees is ₹16000 and that of remaining employees is ₹13750 . Total number of the employees in the factory is:
Answer & explanation
Correct answer: option 2
The average salary of all the workers in a factory = Rs.15,000
Average salary of 250 employees = Rs. 16,000
Average salary of the Rest of the workers = Rs. 13750
Average = Sum of observations / Number of observations
Let the number of employees be "x"
Total salary of all workers = 15000x
Total salary of 250 employees = 16000 × 250 = 4000000
Total salary of rest of the workers = 13750 (x - 250) = 13750x - 3437500
According to question
15000x = 13750x – 3437500 + 4000000
x = 450
