Question

In an exam 34% of the candidates passed and 780 failed Find the number of students who appeared for the exam.

Answer 1

Answer:

let the number of candidates who appeared be 100

no. of candidates who passed = 34

no. of candidates failed= 100-34=66

if 100 are the total students and 66 are failed

what is the total no. of students who appeared when 780 failed

66/100=780/x

100X 780/66=x
