A basketball team scored x points per game in its first n games of the season, and in all the following games it scored an average (arithmetic mean) of y points per game. What was the average number of points per game in its first n + 6 games?	Choose the correct answer:
A) x + 3y/(n + 3)
B) x + y/(n + 3)
C) (x + 3y)/(n + 3)
D) (nx + 3y)/(n + 6)
E) (3x + ny)/(n + 3)
Total points in first n games = nx   Total marks in next 3 games is 3y   So, Average marks in n + 6 games = (nx+3y)/(n+6)   Hence, correct answer will be ((nx + 3y)/(n + 6))
