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
