Pill Problem



Two bottle of pills must be taken to keep you alive. The two must be taken at the same time. Forgetting a pill, taking one and not the other, or taking two of the same one will result in your death. You open the two bottles and pour them both into your hand without thinking. Three pills fall out on your hand. Unfortunately the two pills look, feel, and weigh exactly the same. How do you ensure that you don't take the wrong pill?

Assume that these pills are super expensive and cannot be discarded. So throwing the pills away and just picking one pill each is not a viable option.

its a good thing that the pills are halfable..and necessary to be equal in number in each container , so you can always know if they are 2B&A,2A&B,3A or 3B by recounting the the pills in the bottles..in case of 3A or 3B ,just return the 2 in their bottle and take one of each pill.

You made 2 Assumptions one though is not of as much of a consequence:

1. You don't know if Two or three came from the same bottle.

2. You assume that each prescription is of the same count.

Assumption 2 must be true for, otherwise, you are eventually doomed. So, you can determine

how many pills came from each bottle. If all three came from the same bottle, you have no

problem since you can take one of those each time with one from the other bottle. If two came

from bottle A and one came from bottle B, just take another from bottle B and, take one-half

of each of these four pills at one time, then take the remaining halves the next time.

Of course, TSLF said as much in post #8. So, I can claim no credit here.
