Let the total no. of examiners be x
% of examiners passed =100%-72% =28%

ATQ,
28% of x =392
28x/100 =392
28x=392×100
x=39200/28
x=1400

Total no. of examiners are 1400...

Answer 2

In this question,
Let the total examiner be x.
Passed examiner = 72%
Then, failed examiners
= 100-72 = 28%
Now, as per the question,
28% of x = 392
x = 392*100/28 = 1400.
So, total number of examiners = 1400.
