Correct option is B
Given:
Total number of employees = 40
Number of non-teaching staff = 35
Average salary of all employees = Rs. 4000
Average salary of non-teaching staff = Rs. 4200
Formula Used:
Total Salary of All Employees:
Total Salary=Average Salary×Total Number of Employees
Total Salary of Non-Teaching Staff:
Total Salary of Non-Teaching Staff=Average Salary of Non-Teaching Staff×Number of Non-Teaching Staff
Average Salary of Remaining Staff:
Average Salary of Remaining Staff=Number of Remaining StaffTotal Salary of Remaining Staff
Solution:
Total Salary of All Employees: = 4000 × 40 = 160000
Total Salary of Non-Teaching Staff = 4200 × 35 = 147000
Total Salary of Remaining Staff (Teaching Staff) = 160000 – 147000 = 13000
Number of teaching staff = 40 – 35 = 5
\text{Average Salary of Teaching Staff} =
513000 = 2600
Thus, The average salary of the remaining staff (teaching staff) is Rs. 2600.
