Solution

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.

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.
