Question

in exam 72 percent of total examinees passed.if the number of failures is 392 find the total number of examinees

Answer 1

We know that total percent is always 100%.

Given that 72% passed. so that means (100-72) or 28% have failed.

Let x be the total number of examinee then failed 28% will be 0.28x.

Given that number of failed examinees = 392

then both will be equal

0.28x=392

x=392/0.28

x=1400

Hence 1400 is the final answer.

Answer 2

Let the total no . Of examine paas be x
Failure = 72%
=100-72
=28%
=28/100
0.28
Acc to que
0.28x=392
X=392×100/28
X= 1300
