Question

in an examination 72% of total examines passed if the number of failures is 392 find the total number of examinees​

Answer 1

72% passed. Hence 28% got failed.

Let total no. of examinees be 'x'.

Given 392 failed

=>(28/100)x = 392

x=1400 is the total no. of examinees

Answer 2

Total percent of failures = 100-72 = 28%

Number = 392×100/28

Total number of examinies= 1400
