Sample Question #271 (brainteaser)
I was having lunch with my financial engineering coworkers the other day when someone came up with this question:
We have just had our reviews and received our 2007 bonuses. Everyone in the lunchroom wants to know what the average bonus among the people in the room is. But, alas, no one is willing to divulge his or her own number. Can you think of a way for us to find out the average bonus?
