Here's the Answer ::


=> =>


Let the total number of students be x

Percentage of students who wear glasses = 20%

Percentage of students who do not wear glasses = 100 - 20 = 80%

80% of x = 28


=> According to Question


80% of x = 28
80 /100 × x = 28
4 / 5 × x = 28
4x /5 = 28
4x = 28 × 5
4x = 140
x = 140 / 4
x = 35


So, the total number of students is 35 .
