  2. The idea here does not rely on number of computers BUT the number of players. Therefore, making the assumption of 4 computers is flawed since nothing was mentioned about the number of computers even though the answer you have gotten is correct; if the question changes to having 1 or 2 or 3 computers, your way of thinking will result in wrong answer. The real reason is because there are 4 players playing, so even if it's sharing of computers, say 2 players on one computer, total player time played is still 150x4. This should be the correct way to think...
