Question

In an examination, 91% students passed
If 18 students failed, find how many
students appeared in the examination​

Answer 1

Answer:-

Let total students be "x"

Students failed = 100 % - 91 %

Students failed = 9%

Total students = 9/100 × x = 18

x = 18 × 100 / 9

x = 2 × 100

x = 200

Hence, Students appeared in the examination is 200.

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.
