Solution

The correct option is C

Exactly 25


Let number of newspaper be x,
Number of students =300,
Number of newspapers read by each student =5,
Number of time every newspaper is read =60

It is obvoius to say,
Number of students ×Number of newspapers read by each student = Number of newspapers × number of times every newspaper is read

300×5=x×60x=25

Hence the number of newspapers must be exactly 25.
