Answer 2

Number of students in the class is still less than 50

Solution:

Given, there are less than 50 students in the class.  

Today, only 97.5% of the class is here.  

We have to find how many students are in this class?

Now, let the students strength of class be x.

Then, x < 50.

And, present percentage = 97.5%

Students in class = 97.5% of x

= 97.5/100 $\times$ x

= 0.975 $\times$ x

Here, we are multiplying "x" with a number less than 1. So the result will be less than the number.

Hence the number of students in class is still less than 50
