person tastes very little he will die within 14 hours so if
there are mice to test and 24 hours, how many mices are
required to find the poisoned can?
Answer Posted / kaifi arshu
Ans is 5
let as take can as 1 2 3 4 5 6 ... 30 and mice as A,B,C,D & E
make mice A to drink 1-5 cans
B to 6-10
C to 11-15
D to 16-20
E to 21-25
aft 12hrs check which one is dead A, B, C, D, or E.
If no1 is dead upto 25, then check 26 to 30..
A-26, B-27, C-28, D-29, E-30
-----------------------------------------------------------
If any1 is dead, then check in this way..
for eg.:
if C dies, then take 11-15 cans
A to 11
B to 12
D to 13
E to 14
leave the 15th can..
if A dies then 11 is poisoned, if B dies then 12 is poisoned, if D dies then 13 is poisoned, if E dies then 14 is poisoned, if no1 is dead then 15 is poisoned one..
