Question 67

In a game, $N$ people are in a room. Each of them simultaneously writes down an integer between $0$ and $100$ inclusive. A person wins the game if their number is exactly two-thirds of the average of all the numbers written down. There can be multiple winners or no winners in this game. Let $m$ be the maximum possible number such that it is possible to win the game by writing down $m$. Find the smallest possible value of $N$ for which it is possible to win the game by writing down $m$ in a room of $N$ people.
