The average salary of all 40 employees, including 35 non-teaching staff members, of a school is ₹4,000. If the average salary of the non-teaching staff members is ₹4,200, find the average salary of the remaining staff of the school.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. ₹2,600.
Given that,
The average salary of all 40 employees, including 35 non-teaching staff members, of a school is ₹4,000
The total salary of all employees = 4000 × 40 = ₹160000
If the average salary of the 35 non-teaching staff members is ₹4,200
The total salary of the non-teaching staff members = 35 × 4200 = ₹147000
According to the question
The salary of the remaining staff of the school = 160000 - 147000 = ₹13000
Hence,
The average salary of the remaining staff = 13000/5 = ₹2600
