In a company there are 44 employees. The average salary of 30 employees is ₹4200 per month and the average salary of 10 employees among remaining 14 employees is ₹6200 per month. If the average salary of all employees is ₹7400 per month, then what is the per month average salary of the remaining 4 employees?

Correct option is B

Given:

• Total employees = 44
• Average salary of 30 employees = ₹4200
• Average salary of 10 employees = ₹6200
• Average salary of all employees = ₹7400
• We need to find the average salary of remaining 4 employees

Formula Used:

1. Total salary = Average × Number of employees
2. Remaining salary = Total salary – Salary of known groups

Solution:

Step 1: Total salary of all 44 employees
= 44 × 7400 = ₹325600

Step 2: Salary of 30 employees
= 30 × 4200 = ₹126000

Step 3: Salary of next 10 employees
= 10 × 6200 = ₹62000

Step 4: Remaining salary for the last 4 employees
= 325600 – (126000 + 62000)
= 325600 – 188000 = ₹137600

Step 5: Average salary of remaining 4 employees
= 137600 ÷ 4 = ₹34400

Final Answer:

(b) ₹34400
