In a college of 300 students, every student reads 5 newspapers, and 60 students read every newspaper. The number of newspapers is ___.
Unitary method is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Answer: The number of newspapers is 60
Let's find the number of newspapers.
Let us approach this problem from the perspective of the number of reading sessions:
The total number of students is 300. Each student reads 5 newspapers.
The total reading sessions = 300 × 5 = 1500
In total there are 1500 reading sessions in a day.
Given that, 60 students read every newspaper.
In other words, one newspaper undergoes 60 reading sessions.
Hence, for 60 reading sessions, 1 newspaper is enough.
So, we need to find for 1500 reading sessions how many newspapers are required.
60 × N =1500
N = 1500/60 = 25
Therefore, 25 newspapers are required for a college of 300 students.
