Step-by-step explanation:

Now since 20% were absentees …

Then 80% will b present

Now …it is given that 40 students came in class…

So 80% of x = 40

80/100* x = 40

Which gives …

x= (40*100)/80

=> x= 50

Therefore number of students in a class is 50

And number of students absent is 10 which is the 20% of the total strength of the class ….
