• A. At least 30
• B. At most 20
• C. Exactly 25
• D. None of these

Answer 1

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,
$\text{Number of students}\times \text{Number of newspapers read by each student = Number of newspapers}\times \text{number of times every newspaper is read}$

$\therefore 300\times 5=x\times 60x=25$

Hence the number of newspapers must be exactly 25.
