Boys and Burgers Puzzle.

So sorry! the wording of the puzzle you received is not the same as the answer below. The word ‘each’ was omitted. So here is the correct answer to the puzzle you viewed:

If 3 boys take 3 minutes to eat three burgers, then EACH of the three boys eats ONE burger in three minutes. So ten boys will eat 10 burgers in three minutes. After 10 minutes, they will have eaten 33 1/3 burgers.

Thank you so much to the thinking readers who contacted me. I really appreciate your feedback.

When I was 2 years old my brother was half of my age. Now, I’m 100 years old. What’s the age of my brother right now?

If you make the assumption that statement “When I was 2 years old my brother was half of my age.” to mean that the siblings must have the same birthday, or you take the phrase “Now, I’m 100 years old.” to mean that you are referring to it being the exact same date 100 years in the future, then the answer is 99.
However, if you take the statements to mean their commonly used meaning of “At some point, or for most of the year, when I was 2, my brother was 1.” then the answer could validly be 98, 99, or 100.
