In a recent roundup of questions Goldman Sachs has been known to ask, we came across this classic brainteaser: "Suppose you had eight identical balls. The remaining one is defective and either heavier or lighter than the rest. You have a set of balance scales which will give 3 possible readings: Left = Right, Left > Right, or Left < Right (ie Left and Right have equal weight, Left is Heavier, or Left is Lighter). Each ball can go into any Two identical small conducting balls B_1 and B_2 are given −7 pC and + 4 pC charges respectively. Distinct objects into identical bins is a problem in combinatorics in which the goal is to count how many distribution of objects into bins are possible such that it does not matter which bin each object goes into, but it does matter which objects are grouped together.
