In a billiards match, player A can give player B a 20-point advantage in a 60-point game, and A can also give player C a 30-point advantage in the same 60-point game. How many points can B give C in a 100-point game?

Explanation

Player A scores 60 points, B scores 40 points, and C scores 30 points in the 60-point game. To find how many points B can give C in a 100-point game, calculate C's score when B scores 100: (100 * 30) / 40 = 75 points. Therefore, B can give C the difference between 100 and 75, which is 25 points.
