GiveN:

% of students passed = 91%

No. of students failed = 18

To FinD:

How many students appeared in the examination?

Step-wise-Step Explanation:

Let the total no. of students appeared in the examination be x. It is given in the question,

91% of the students passed.

Then % of failed students = 100% - 91% = 9%

According to question,

⇒ 9% of x = 18

⇒ 9/100 * x = 18

⇒ x = 18 * 100 / 9

⇒ x = 200

Thus, the total no. of students appeared = 200.
