• 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..
