You and your 3 friends are out to dinner. You want to know Bob's favorite number. None of them lie, but they are not necessarily correct in their statements.
You: (to Bob) What is your favorite number?
Bob: 1488 is my favorite number.
Barry: I'm sorry. Bob multiplies every number he says by 2.
Bill: I'm sorry, Barry divides every number he says by 4 to make up for Bob's exaggerations.
Bob: I'm sorry. Bill is not very bright. He adds 8 to every number he mentions.
