What is different??

Question

For the problem of paint cost in code coach i tried this 2 codes:-
1st
n = int(input())
total = n*5 + 40
tax = total/10
print(int(round(tax+total,0)))

2nd
n = int(input())
total = n*5 + 40
tax = round(total/10,0)
print(int(tax+total))

If i use the 1st code the 3rd test case fails and if i use 2nd code 4th test case fails.
Can some body help me understand what is wrong in both of these codes.

Answer 2

The Task description says that you should "round up" the result. In the code "round"() is used, but this is rounding to the next possible integer. This can be a rounding up, or a rounding down. So you have to use the "ceil()" function, which is always rounding up to the next integer. Therefore you have to import math like:

from math import ceil

then use ceil(...) instead of round()

I solved the problem by the following method👇

n = int(input())
total = n*5 + 40
tax = total/10
tx =str(tax)
if int(tx[-1])>=5:
tax = int(tax)+1
else:
tax = int(tax)

print(tax+total)
