In a school, 21 student read Maths, 26 reads Physics and 29 read Chemistry. If 14 students read Maths and Physics, 15 read Physics and Chemistry, 12 read Chemisry and Maths and 8 read all three subjects, then find the total students in the school.

Text Solution

AI Generated Solution

To find the total number of students in the school who read Maths, Physics, and Chemistry, we can use the principle of inclusion-exclusion. Let's denote: - Let \( M \) be the number of students who read Maths. - Let \( P \) be the number of students who read Physics. - Let \( C \) be the number of students who read Chemistry. - Let \( M \cap P \) be the number of students who read both Maths and Physics. - Let \( P \cap C \) be the number of students who read both Physics and Chemistry. - Let \( C \cap M \) be the number of students who read both Chemistry and Maths. ...
