In a town, a survey was conducted among 500 residents regarding their preferred modes of transportation: Car (C), Bus (B), and Bicycle (Y). The results were as follows: 250 residents use Cars, 220 use Buses, and 180 use Bicycles. 100 residents use both Car and Bus, 90 use both Bus and Bicycle, and 80 use both Car and Bicycle. If 50 residents use all three modes of transportation, how many residents use none of these three modes?
