Just a tip - How to answer the McD question: McD are spread worldwide - so assume some figures for the leading consumer nations. For ex - 70% of US population, 50% of Japanese population etc consume at least 1 McD burger/meal a day. Now compute the average price of a McD burger/meal. Multiply the two and you have average revenues per day. Average price * no of burgers/meals sold per day = Average revenues. Average revenues per day * 30 * 12 = annual revenues. Follow the same formula for all product lines and add them up. Hope this helps.
