Question

in an examination 91% of the candidates passed and 18 failed how many candidates appeared in the examination

Answer 1

total candidate = x
candidate passed =91%
candidate failed =18
x=91/100 +18
91/100 +18 = 109/100

Answer 2

Number of candidate appeared in the examination is 200.

Step-by-step explanation:

It is given that,

Percentage of student who passed the exam = 91%

Since total percentage of candidate appeared in the exam = 100%

Percentage of student who failed the exam = 100%-91%

                                                                         =9%

According to question ,

9% of total student appeared in the exam= 18

1% of total student who appeared in the exam = 2

Total number of student who appeared in the exam =$2\times 100$

                                                                                      = 200

Hence,Number of candidate appeared in the examination is 200.
