Answer the next 5 questions based on the information given below.
300 students of CAT4ALL institute wrote CAT exam in 2023. Two-thirds of the students could not clear cutoff for any of the three sections in the exam. For every two students who cleared cutoff for section only section A, one more cleared the cutoff of only section B. For every five students who could clear cutoff only section C, three less could clear cutoff of only section B. The number of students who could clear cutoff of both B and C was 30 and the ratio of students who could clear cutoff of both A and C to those who could clear cutoff of both A and B was 5 : 7.
The number of students who could clear cutoff of exactly two sections was 30 and the ratio of the number of students who could clear cutoff of both C and B but not A to the number of students who could clear cutoff of both A and C but not B is 2 : 1. How many students could clear cutoff of all three sections?
