A company shares a bonus of 500 Pounds between six employees whose years of service are consecutive whole numbers. Five of them receive the same whole number of Pounds for each year of their service. But the sixth, their manager Kate, receives a higher whole number of Pounds for each of her years of service.
Pat did not receive the lowest bonus but received 20 Pounds less than Kate even though he had been with the company for one year longer.
How much did Pat receive?
