if there are 30 cans out of them one is poisoned if a
person tastes very little he will die within 14 hours so if
there are mice to test and 24 hours, how many mices are
required to find the poisoned can?
Answer Posted / ann
5 mice
Let A, B, C, D, E be the mice
Give
Can 1 to E (00001)
Can 2 to D (00010)
Can 3 to E,D (00011)
.............
Can 29 to A,B,C,E (11101)
Can 30 to A,B,C,D (11110)
Poisoned CAN can be found after 14 hrs by looking which mice are dead. ie CAN number corresponding to binary output.(take 1 if the mouse is dead and 0 if it is alive and dont forget the order)
example
If A,C,D are dead ===>CAN no 22 is poisoned (10110 is binary of 22)
and if B is dead ===>CAN no 8 is poisoned (01000 is binary of 8)
| Is This Answer Correct ? | 22 Yes | 5 No |
