The "Halloween Candy" question in Code Coach

Question

https://www.sololearn.com/coach/4?ref=app

I have devoted almost an hour to solving this simple looking question but am still unable to get all the five code tests correct. It shows the code to be incorrect after two tests i.e. on the third one.
Can someone please point out the mistake.
This is my code:

a=int(input())
b=(2/a)*100
print(round(b))

Answer 1

it says **round up**

use math.ceil() instead of round()

Answer 2

Thanks Slick , it worked
