Question

In an examination 92% of the candidates passed. If the number of candidates who
failed is 400. Find the total number of candidates who appeared in the
examination.​

Answer 1

Answer:

total number of candidates appeared in the exam =x

no of candidates failed =400

no of candidates passed =92% of x

no of candidates failed+no of candidates passed=total

400+92%of x=x

400+92x/100 =x

400+23x/25 =x

10000+23x/25 =x

10000+23x=25x

10000=25x-23x

10000=2x

x=10000/2=5000

therefore, total number of candidates who appeared in the

examination are 5000

Answer 2

Answer:

5000 candidates

Step-by-step explanation:

92% passed in exam.

So, (100-92)% = 8% failed in exam.

Total candidates be x .

Failed students : 400

8% of x = 400,

(8/100)× x = 400,

x = (400×100)/8,

x = 5000.

So, Total candidates are 5000.
