Question: A company has 100 employees with an average salary of $5000. If 10 employees leave with an average salary of $6000, what is the new average salary?
Options:
Correct Answer: $4950
Solution:
Total salary of 100 employees = 100 * 5000 = $500000. Total salary of 10 employees leaving = 10 * 6000 = $60000. New total salary = 500000 - 60000 = $440000. New average = 440000 / 90 = $4888.89, which rounds to $4900.
