Answer:
the answer is here
Step-by-step explanation:
Let the no. of candidates be x
percentage of candidates passed=89
no. of candidates passed =89x/100
no. of candidates failed =220
therefore according to question,
x-89x/100=220
100x/100- 89x/100= 220
11x/100=220
x=220x100/11
x = 2000
no. of candidates appeared = 2000
no.of candidates passed = 89/100×2000
=1780 passed
