In my last post, I said that our mind is limited, but it can still have considerable power. I thought it would be fun to give you problem to solve at this point in the middle of all the serious talks. So here we go.
There are ten identical containers with each holding ten identical pills. Nine of the containers hold pills weighing 10 mg each and one container holds ten pills weighing 9 mg each. All pills look exactly alike. There is an electronic scale available for your use. The problem is that the batteries in the scale are so weak that there is only one weighing left. So, how would you weigh the pills just once and identify the container holding the 9 mg pills?
The solution is not that obvious. Some people have solved the problem in a couple of hours, but others in a couple of weeks. Try your best, but don't lose any sleep over it.
