Answer / avinash
there is 3 mice....
a,b,c
first we drink one cane to every rat...
after one hour again drink one cane to every rat...
and so on till 10 hour... In 10 hour every rat drink 10 cans so all rat drink 30 cans...
if A OR B OR C died from poison in 14th hour so they died from 1st cane OR 2nd cane OR 3rd cane respectively
if died in 15th hour they died from 4th,5th,6th cans respectively....so on
In 24th hour they died from 28th,29th,30th cans respectively...
so we can determine which cane is poisoned..

mice will taste 30th can in 30th min.
if mice die in 14 hours then fist can is poisoned.
if mice die in 14 hours 1 min then second one is poisoned.
if mice die in 14 hours 2 min then third one is poisoned.

if mice die in 14 hours 29 min then last one is poisoned.
finally we need 1 mice and 14 hours 30 min for testing thats it.

Answer / amarish
In my view....
answer will be 29...
REASON is....
if u test for 1 mouse, u hv to wait for 14 hours to check
whether it is poisoned or not.
Now since u hv only 24 hours to check, so u hv to employ
mice at first time u can't go for further checking....
