Question

in an examination 72 of the total examination passed if the number of failures is 392 find the total number of examiness​

Answer 1

Answer:

examiners+examinees = 72+392

Answer 2

Assume that 100 candidate took the examination.

In that 72% of them are passed =72 candidates

In that failed candidates =(100−72)=28

Number of candidates if 28 of them failed =100

Number of candidates if 392 of them failed =(100/28)×392

=1400

∴ the total number of examinees is 1400
