Question

in an examination 35% of the students passed and 455 failed. how many students appeared in the examination? ​

Answer 1

hey....♥

let total number of students =x

students passed =35%

remaining students who are failed=100-35

=65%

now...

number if students failed=455

so...

65% of x=455

65× x/100 = 455

x = 455 ×100 /65

x = 7×100

x= 700

SO....TOTAL NUMBER OF STUDENTS WHO

APPEARED FOR EXAMINATION ARE 700
