Best answer
Correct Answer - Option 2 : Rs.31,000

Given:

When manager is included,

Average increase in salary = Rs. 1000

Salary of manager = Rs. 95,000

Total employees excluding manager = 64

Formula Used:

Average = (Sum of salaries) / Number of people

Calculation:

Let the average salary of the company excluding the manger be x.

After addition of Manager's salary, the average increases by 1000

⇒ 64x + 95000 = 65 × (x + 1000)

⇒ 64x + 95000 = 65x + 65000

⇒ x = 30,000

The final average salary = 30,000 + 1000 = Rs. 31000

∴ The final average salary of the company is Rs.31,000.
