There are 30 beer bottle nd one is poisoned. we have mice who will die after 14 hrs after drinking poisned beer. In 24 hrs we have to find poisoned beer bottle. How many no of mice we require to find out poisoned bottle.

• 1 mice & 14hrs 28mins are enough to get the result...
  At 1st min the mice tastes 1st can & dies at 14hr
  At 2nd min the mice tastes 2nd can & dies at 14hr.1Min
  At 3rd min the mice tastes 3rd can & dies at 14hr.2Min
  .
  .
  .
  At 29th min the mice tastes 29th can & dies at 14hr.28Min
  If the mice is till alive after 14hr.28Min then the poison will be in the 30th Can....
  
  So no death and result achieved in the last case...

• 1 mouse required,as 24-14=10,so 10hrs/30=20min.if 1st bottle is poisioned mouse dies after 14hrs 20 min , 2nd bottle 14hrs 40min, 3rd 15 hr and so on............. or we can even short the time to 10 mins
