[SOLVED] Why this test cases becomes false everytime??

Question

Actually I just try to solve paint costs problem. I tried this in Python and C language. In both, Case 1,2 and 5 are solved. But everytime case 3 and 4 becomes false. What's wrong here?, I cannot understand this.

Here is the code in python:

a = int(input())
sum = a*5 + 40
tax = int(sum/10)
total = sum + tax
print(total)

Thanks!!

Answer 1

it says rounded "up" to the nearest whole number ,so you need to use ceil method of math class for that purpose
a = int(input())
sum = a*5 + 40
import math
tax = math.ceil(sum/10)
total = sum + tax
print(total)

Answer 3

Here is the code in python:

a = int(input())
sum = a*5 + 40
tax = sum/10
total = sum + tax
print(round(total))

Thanks!!
