Correct Answer - Option 3 : 1000
Given:
400 students passed in an examination
60% students failed
Calculation:
Number of passed students= 400
Percentage of failed students = 60%
Percentage of passed students = (100 - 60)%
= 40%
Let total number of students appeared be x
⇒ 40% of x = 400
⇒ (40/100) × x = 400
⇒ x = (400×100)/40
⇒ x = 10 × 100
⇒ x = 1000
∴ Total students appeared (x)=1000
