You have 8 objects of similar size, but one object weighs a little bit more than the others. Given a balance scale, you must find out which object it is, but you may only use the scale twice.
What do you do?

Best ResponseYou've already chosen the best response.0Great; they say it can actually be done with only 2 "weighing" steps but still, I wanna see your answer!

Best ResponseYou've already chosen the best response.1Just divide the 8 things into two groups, and place it in each of the pans of your balance.

Best ResponseYou've already chosen the best response.0i am guessing adg knows because it is related to computer algorithms.

Best ResponseYou've already chosen the best response.1Now solve this: There are 10 cigarette packets, each containing 10 cigarettes. One of the packets contain cigarettes which are a bit heavier than the cigarettes in any of the other packets. Although each cigarette in anyone packet weighs the same. Now with just one weighing you need to find out the culprit box.
