Problem of the Week

for Tuesday, September 27, 2011

Imagine this: You have four bottles of liquid. One of the bottles contains a poison strong enough to kill a rat by morning if the poison is taken at night. Only a little bit of the solution is required to provide a lethal dose. if you have two live rats at your disposal and one night to experiment, how can you determine which bottle contains the poison?
