My issue
diff is the deficit Chef needs to make up. Save is the raw money he saves per session(he gets a a D% discount but needs to pay one). N should be the answer then. And this works fine on my local computer, but submitting always gives a RE
My code
# cook your dish here
import math
x = int(input())
for a in range(x):
i = input().split(" ")
d = int(i[0])
m = int(i[1])
b = int(i[2])
diff = m-b
save = (m*(d*0.01))-1
n = math.ceil(diff/save)
if b>=m:
print(0)
elif save <= 0 or n > b:
print(-1)
else:
print(n)
