Answer:
53,47
Explanation:
If 1 van and 6 buses with 372 students, then each bus and van had 372/7 = <<372/7=53>>53 students.
If each bus and van had the same number of students, then 4 vans and 12 buses had 453 = <<453=212>>212 students.
If 4 vans and 12 buses with 780 students, then each bus had 780-212 = <<780-212=568>>568/12 = <<568/12=47>>47 students.
Therefore, 1 van can hold 53 students and 1 bus can hold 47 students. Answer:{53,47}.
