The average salary of a company's eight employees is Rs. 6000 per year. If the average salary of the first 4 employees is 5500 and the average salary of the next 2 employees is Rs. 7000, what is the average salary of the remaining 2 employees to maintain the company's average salary?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Rs. 6000.
Total salary of all employees = 8 × 6000 = Rs. 48000
Total salary of the first 4 employees = 4 × 5500 = Rs. 22000
Total salary of the next 2 employees = 2 × 7000 = Rs. 14000
The total salary of the remaining 2 employees be ( x )
The total salary of all 8 employees is the sum of the salaries of these three groups,
⇒ 22000 + 14000 + x = 48000
⇒ 36000 + x = 48000.
⇒ x = 48000 - 36000 = 12000
Average salary of the remaining 2 employees = 12000 / 2 = Rs. 6000
