Question

Ek exam me 35% student pass hue 455 fail hue.total number student ki number batao

Answer 1

percentage of students failed=100%-percentage of students passed
=100%35-%
failed=65%


failed Number of students=455
let total number of students be x
so
65/100×x=455
0.65x=455
x=455/0.65
x=700

so total number of students=700


also number of students failed =455
number of student passed=35/100x700

number of students passed =245



verifying our answer
total number of students=no of students:-


passes+failed
=245+455
=700
