Answer 2

The total number of students is 3200

Given:

In an exam, 96% passed,

128 students were failed.

To find:

The total number of students.

Solution:

Let 'x'  be the total number of students

In an exam, 96% passed,

Failed % = 100 - 96

Failed = 4%

Number of students failed = 128

Therefore

4% of x = 128

$\frac{4}{100}$ × $x$ = 128

x = 128 × $\frac{100}{4}$

x = 128 × 25

x = 3200

The total number of students is 3200
