Post your answer if you have any, I'll tell you if you got it right or wrong. To give more challenge to others, it'll be appreciated if you post me a private note answer.
1) There are 10 bottles of pills. 9 of which has 2.0g/pill pills in it. and 1 bottle with 2.1g/pill pills in it. you are given a weighing scale, but you can only weigh anything on it once. ie, you are only allowed to read off A reading. How do you know which is the bottle with the heavier pills?
2) You have 9 bottles. One of them is slightly heavier then the others. You have a balance which you can use twice. ie, you can take off and put stuff on it 2 times only. How do you know which one is the heavier one?
I'll post the answer some time later.. to keep you guys in suspense for the time being. haha... i got both of them correct!! ;> so proud of myself.. ;P You can do it too! I'll notify you if you get the correct answers though... ;)
