Burger King Leadership DevelopmentProgram interview questions

Asked for difference between managing, leading, and working people. There were 3 brain teasers, and for each one you needed to explain your thought process. First was the angle for the time on a clock, the second was how many people were eating dinner at a certain time, third was you were the owner of a cookie bakery, your sales have cut in half, and your cookies are coming out burnt. How do you solve this problem?
