The average monthly salary of 60 employees of a factory is Rs. 29900. If two officers are getting Rs. 90000 each and the average salary of 8 supervisors is Rs. 65000, then what is the average salary (in Rs.) of the remaining employees?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 21880.
The sum of the monthly salary of 60 employees = 60 × 29900 = 17,94,000.
Sum of the salary of two officer = 90000 × 2 = 1,80,000.
Average salary of 8 supervisors = 65000 × 8 = 5,20,000.
Sum of the salary of remaining employees = 1794000 - 5,20,000 - 1,80,000 = 1094000.
The average salary of these 50 employees = 1094000/50 = 21880.
