AIG, an international insurance and financial services organization, recently announced that the performance of employees would be rated on a scale from 1 to 4. The top 10% of employees would receive a 1 rating, 20% of the employees would be rated with a 2, and 50% would be rated with a 3. The remaining employees would receive a 4 rating. The rating scheme is known as a forced ranking system. It was begun after the government bailed out AIG and forced the company to link compensation to performance. Suppose the Wilmington, Delaware, facility of AIG has 450 employees. Determine the number of employees who can receive each rating.
