Paul and James shot 100 arrows, each managing to hit the target 50 times. With the score tied they broke for lunch. After the break, the shooting was not as sharp. Paul shot 89 arrows but only managed to hit the target 13 times. James shot 50 arrows without hitting the target once. Paul claimed that his percentage after the break was better than James', so therefore, he must be the better shot. James naturally disagreed. Who had the better average for the day?
