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..
