Question

in a competitive examination 84 percent of the candiadates passesd and 780 failed find the number of students who appeared for exam ​

Answer 1

Answer:

Step-by-step explanation:

Solutions :-

We have,

Percentage of passed candidates = 84%

Failed candidates = 780

Let the total percentage of Candidates appeared in examination be 100%

Find the Percentage of failed candidates :-

= 100% - 84%

= 16%

Now,

Let the total number of Candidates appeared in examination be x

Find the value of x :-

a/q

=> 16% of x = 780

=> 0.16 × x = 780

=> 0.16x = 780

=> x = 780/0.16 = 4875

Therefore, the total candidates appeared in the examination  is 4875

Answer 2

Answer:

5655 students came for exam

Step-by-step explanation:

84% candidate passed so 16% candidate failed

so,

16% of x = 780

16/100*x = 780

x =780*100/16

x = 4875

total students = 4875 + 780 = 5655
