A friend of mine had an interview a couple weeks ago with Google Inc.He provided me a list of just some of the questions he was asked. I’veadded a few more from others I have talked to who had interviews withthe internet giant, Google, as well. See if you can answer them. Manyare open ended with several right answers, therefore I did not providethe answers.

9. Every man in a village of 100 married coupleshas cheated on his wife. Every wife in the village instantly knows whena man other than her husband has cheated, but does not know when herown husband has. The village has a law that does not allow foradultery.

13. Four people need to cross a rickety rope bridgeto get back to their camp at night. Unfortunately, they only have oneflashlight and it only has enough light left for seventeen minutes. Thebridge is too dangerous to cross without a flashlight, and it’s onlystrong enough to support two people at any given time. Each of thecampers walks at a different speed. One can cross the bridge in 1minute, another in 2 minutes, the third in 5 minutes, and the slow poketakes 10 minutes to cross. How do the campers make it across in 17minutes?
14. You are at a party with a friend and 10 peopleare present including you and the friend. your friend makes you a wagerthat for every person you find that has the same birthday as you, youget $1; for every person he finds that does not have the same birthdayas you, he gets $2. would you accept the wager?

(Hint: One pirate ends up with 98 percent of the gold.)
