I seek for the help of an Expert here. Thanks Hi Roland2rule, Let's take a look at your question. After 6 games, team B had an average of 61.5 points per game. We can find the total points scored in these 6 games using average formula. $$Average\ =\ \frac{Sum\ of\ points\ }{Number\ of\ games}$$ $$61.5\ =\ \frac{Sum\ of\ points\ }{6}$$ $$\ Sum\ of\ points\ =61.5\times6=369$$ Therefore, Sum of points in first 6 games is 369. The points scored in 7th game is 47. $$Points\ scored\ in\ 7\ games\ =\ 369+47=416$$ We can now find the minimum points that should be scored, so that the total gets above 500, let's say 501, as: $$501-416=85$$ Therefore, option A is correct. Hope it helps. I am available if you'd like any follow up. _________________ GMAT Prep From The Economist We offer 70+ point score improvement money back guarantee.

We're asked for the number of points the team would need to score in game 8 to get its total ABOVE 500. The math behind this question can be solved in a couple of different ways. To have a total ABOVE 500, the average score for the 8 games would need to be ABOVE 500/8 = 62.5 In the first 6 games, the average score was 61.5, so the team was 6(-1) = -6 points away from that exact average. In the 7th game, the score was 47, so with this score the team is 62.5 - 47 = -15.5 points away from that exact average. This means that in the 8th game, the team has to 'make up' all of those missing points AND get a bit above 62.5.... 62.5 + 6 + 15.5 = 84 + some extra. There's only one answer that matches...

After game 7, the team had a total of 369 + 47 = 416 points, so the team needs another 501 - 416 = 85 points to get above 500.
