A survey was conducted among 300 students regarding their favorite sports: Football (F), Basketball (B), and Tennis (T). The results indicated that 150 students liked Football, 130 liked Basketball, and 110 liked Tennis. Additionally, 80 students liked both Football and Basketball, 70 liked both Basketball and Tennis, and 60 liked both Football and Tennis. If 40 students liked all three sports, how many students liked exactly two of the three sports?
