Question

On a particular day, 16% of the students were absent in a class. If 42 students were present on that day, find the total strength of the class.

Answer 1

Percentage of students absent = 16%
Percentage of students present = (100-16)% = 84%
No. of students present = 42
Let the total no. of students be x.

So,
84% of x = 42
84x = 42*100
84x = 4200
x = 4200/84
x = 50
The total strength of the class is 50.
