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 + 4 games? Choose the correct choice from the following choices
A) x + 3y/(n + 3)	B) x + y/(n + 3)	C) (x + 3y)/(n + 3)	D) (nx + 3y)/(n + 4)	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 + 4 games = (nx+3y)/(n+4)   Hence, correct answer will be ((nx + 3y)/(n + 4))
