Question

in a competitive examination ,84%of the canditates are passed and 780 failed .find the number of students who appeared for examination

Answer 1

Solutions :-


Given :

Passed candidate in percent = 84%
Failed candidates = 780

Failed candidates in percent = (100 - 84)% = 16%

Let the total number of student appeared in examination be x


A/q

=> 16% of x = 780
=> 0.16 × x = 780
=> 0.16x = 780
=> x = 780/0.16 = 4875



Hence,
The total number of student appeared in examination = 4875

Answer 2

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

Answer : Total Candidates appeared in examination = 4875
