There are 100 light bulbs lined up in a row in a long room. Each bulb has its own switch and is currently switched off. The room has an entry door and an exit door. There are 100 people lined up outside the entry door. Each bulb is numbered consecutively from 1 to 100. So is each person. Person No. 1 enters the room, switches on every bulb, and exits. Person No. 2 enters and flips the switch on every second bulb (turning off bulbs 2, 4, 6...). Person No. 3 enters and flips the switch on every third bulb (changing the state on bulbs 3, 6, 9...). This continues until all 100 people have passed through the room. How many of the light bulbs are illuminated after the 100th person has passed through the room?

Phone case interview: The company has an online document centre which keeps track of all of the info about its customers. We offered our customers a free option to enroll in e statements and stop receiving paper statements. The enrollment numbers are below our expectations. We want to launch a marketing campaign. What are some of the factors that you would consider to design such a campaign? List them and briefly explain. Now, I have some data for you. The marketing dept has determined that it would send across 150,000 emails to customers based on two different strategies. Each email costs 25 cents and the lifetime savings for each customer enrolled will be $20. For the first strategy, the customer receives a one time statement credit of $15 and under the second strategy, the customer receives a credit of $5. Which strategy would you prefer and why? When asked about response rates, the interviewer gave response rates of 15% and 10% for the two strategies.
