There are 100 bottles of a drink, out of which only one bottle is poisoned. Anyone who tastes the drink from the poisoned bottle would die in one hour. However, there is no harm if the drink from other bottles is tasted. A test is to be conducted using rats to identify the poisoned bottle. What is the minimum number of rats needed for the test if the poisoned bottle is to be identified in exactly one hour time? Assume that the time taken by the rats to drink the contents of the bottle is negligible and that rats can drink the contents of as many bottles as we make them to drink.
How do we solve this question?
