Step-by-step explanation:
1. Let number of candidates be x
no. of candidates passed=86/100*x
no. of candidates fail=70.
therefore,86/100*x+70=x
=43/50x+70=x
=70=x-43/50x
=70=7/50x
=70*50/7=x
=x=500

Answer:
430

passed - 86%
failed -. 70 students
it there by given that (100-86)= 14% students failed
total no of students failed- 70
let the total students be appear then,
14%of x = 70
14/100 * x = 70

x= 7000/14
x= 500
passed: total-failed
500-70= 430
