Question

In a exam 14% students failed and 559 students passed determine the number of students who failed

Answer 1

it means 86% students passed..
let the total number of students be X
86% of X = 559
X×86/100=559
X=559×100/86
14% students failed
so
X×14/100=no. of students failed
=559×100×14/86×100
=559×7/43
=13×7
=91
thus 91 students failed

Answer 2

Answer:

91

Step-by-step explanation:

it means 86% students passed..

let the total number of students be X

86% of X = 559

X×86/100=559

X=559×100/86

14% students failed

so

X×14/100=no. of students failed

=559×100×14/86×100

=559×7/43

=13×7

=91

thus 91 students failed
