• If mouse would die exactly after 14 hrs then definitely 1 will be the answer but here the given condition says that mouse will die within 14 hrs.
  so this question will be solved by set theory.
  answer is following
  total beer bottles = 6
  drinking strategy
  bottle1 : mouse1
  bottle2 : mouse2
  bottle3 : mouse3
  bottle4 : mouse1 and mouse2
  bottle5 : mouse2 and mouse3
  bottle6 : mouse3 and mouse1
  on the basis of death of mice set we can decide the poisoned bottle
  
  in this question upto 2 bottle answer will be 1 because 2^1 = 2
  similarly upto 4 bottles answer will be 2 because 2^2 = 4
  for upto 8,16,32,64,128 bottles answer will be 3,4,5,6,7

• only one mouse is required because
  there are 30 cans and let the mice tastes the cans at 5 min time interval and note the time at which the mice taste the particular can so the total time taken by the mice to taste all the cans is 1 hr 15 min so and note the time at which the mice dies and substratc 14 hrs from it and check which can the mouse had tasted at that time

• 2^a>b
  where a is the no. of mice required and b is the no. of cans
  2^a>30=5 so we require 5 mice.This is the case when the mouse dies within some hours and if we want to know when the case is "exactly "some hours then it will always be 1.
