Answer 1

Answer:

The total number of students =300

one student read 5 papers

so number of news paper read by student =300×5

every (one ) newspaper read by 60 students

let number of newspaper be = x

then number of news paper read by student =60x

so

60x=300×5

60x=1500

x=1500/60

x=25

then number of newspaper =25
