there are 30 cans out of which only 1 is poisoned. if a person tastes very little, he will die within 14 hours. if there are mice to test and 24 hours, how many mice are required to find the poisoned can?

• the language here is tricky...
  
  it`s written within 14hrs not at exactly 14th hrs so no of mice req. would be 29
  
  if first 29 dnt die then last bottle will have the poison....
  
  but please tell me what will be right to mark the answer in TCS apti???

• one mice is required
  for 30 cans take 30 time intervals(0.0,0.5,1,1.5,.....)
  i.e after tasting the 30 cans the mice will died note the time
  and subtract intervals from that time(mice died time) exactly we get 14 hours
  on one particular can i.e poison can

• 2^5=32(app. near to 30)
  2^0,2^1,2^2,2^3,2^4......=> 5 mice are required to to find poisoned can...

• 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...

• In the question there is no information of dying duration for mice. there's only given "if a person tastes very little, he will die within 14 hour". I don't know how everyone has calculated without having appropriate data.

• Assign binary codes to 30 cans. you need 5 bits to represent all 30. Pick 5 mice to represent each bit. Have a mice taste all the cans for which the corresponding bit is one. After 14 hours, some will die and some wont. Set 1 for the former and 0 for the latter. The corresponding bit representation is the poisoned can.
