​

Answer 1

Answer:

3) exactly 25

Step-by-step explanation:

Given:-

#1student read 5 newspaper

In other words we can say 5 attempts we're taken by a student to read 5 different newspaper

# 60 students read 1 newspaper

In other words we can say 60 attempts were taken by 60 students to read a single newspaper or we can say 1 newspaper will go through 60 different sessions

#As 1 student read 5 newspaper (given).

Then 300.students read 1500 newspapers (300×5=1500). Or we can say 1500 attempts were taken by 300 students to read 1500 newspapers . Or we can also say that 1500 newspapers will through 1500 different sessions .

Let us assume that total no of news paper be x

As 1 newspaper was readed by 60 students

NOW x newspaper was readed by 60x students

Or we can say that x(total no of newspaper ) will go through 60x sessions .

hence

1500=60x.

x=25(exactly)

1500 will be equal to 60x because

1500 is total sessions available in this particular event and 60x is total possible sessions for total newspapers which is x here

Hence here in this event total possible session is 1500 only not more or less ….

Therefore 1500=60x …
