5 DEATH RAT

:

Where X = Number of wine bottles

Z = Hours for poison to effect

Y = Hours to find a poisoned bottle

import math

#X wine bottles

X=1000

#Z hour time after which the poison works

Z=24

#Y hour time to find the poisoned bottle

Y=48

T = Y/Z

print ("Number of rats required to find the poisoned bottle: ", end="")

print (math.ceil(math.log(X,T+1)))

Output:

Number of rats required to find the poisoned bottle: 7

Now if X=1000

Z=1

Y=1

Then output:

Number of rats required to find the poisoned bottle: 10

Now if X=240

Z=24

Y=48

Then output:

Number of rats required to find the poisoned bottle: 5
