Explanation
Both the quantities are the same.If every student read 5 newspapers, total number of newspapers printed = 5 * 400 = 2000.
Now each type of newspaper should be read by exact 40 students. Therefore the number of types of newspaper needed = 2000/40 = 50.
Therefore, you need 50 types of newspaper with 40 copies of each type for 400 students.
