Which is heavier 8 marbles that are exactly alike except that one of them is slightly heavier than the others I then give you a balance scale and ask you to determine the heavier marble in 3 weighings?
Weighing 1: Weigh any four against any other four. The set containing the heavier marble will be heavier. Weighing 2: Weigh any two from this heavier set against the other two from the set. The pair containing the heavier marble will be heavier. Weighing 3: Weight the two marbles from the heavier pair against one another and you have the odd marble. Simple! ...

8 marbles are exactly alike except that one is slightly heavier than the others how do you determine the heavier marble in 2 weighings?
Pick 6 marbles. Weigh 3 against 3. If they balance, then weigh the other two against each other to find the heavier one. If they don't balance, look at the three that are heavier. Pick 2 and weigh them against each other. If they balance, then the 3rd marble in that group is the heavier one. If they don't balance, you have the heavier one. ...
