Question

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

Answer 1

total % failed =
100%-72%=28%
total examinees be x
28% of x = 392
28x/100=392
x=392×25/7
x=56×25
x=1400 = total examinees

Answer 2

Answer:

$\red { Total \: number \:of \: examinees }\green{=1400}$

Step-by-step explanation:

$Let \: total \: number \:of \: examinees = x$

$Number \: of \: examinees \: passed = 72\%$

$Number \: of \: examinees \: Failed\\ = (100-72)\%\\=28\%$

$Number \: of \: failures = 392\: (given)$

$28\% \:of \: x = 392$

$\implies 28\% \times x = 392$

$\implies \frac{28}{100}\times x = 392$

$\implies x = 392 \times \frac{100}{28}=1400$

Therefore.,

$\red { Total \: number \:of \: examinees }\green{=1400}$
