A group of 100 students were surveyed about their favorite subjects: Mathematics (M), Science (S), and Literature (L). The results showed that 50 students liked Mathematics, 45 liked Science, and 40 liked Literature. It was also found that 20 liked both Mathematics and Science, 18 liked both Science and Literature, and 15 liked both Mathematics and Literature. If 10 students liked all three subjects, how many students liked none of these three subjects?
