  1. Assume that you have just heard of a scandal and that you are the first one to know. You pass it on to 4 persons in a matter of 30 minutes. Each of these 4 persons in turn passes it to 4 other persons in the next 30 minutes and so on.

    Assume that no one hears it more than once and that the world population is 5.6 billion.

    How long will it take for everybody in the world to get to know the scandal?

    This is a math one

    I think it's safe to assume that by "and that the world population is 5.6 billion" he means static, that people that are born don't matter (they wouldn't know about a scandal anyway)

    5.6 billion = aprox 4^22.83, 22.83x30min = 685min. pardon me if i am wrong, for i m not too great with math, despite being azn
