21% student passed in exam. if 3257 students are passing, how many student are appear in exam.

In the given question, it has been given that the number of students passing the examination is 3257. Also it is given in the question that the percentage of students that passed the examination is 21%. It is required to find out the number of students appearing in the examination.

Let us assume that the number of students appearing in the examination = X

Then,

The number of students passing the examination = 21X/100

So we get the equation

21X/100 = 3257

21X = 3257 * 100

21X = 325700

X = 325700/21

= 15509.52

So the number of students appearing in the examination is 15510 approx.
