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 + 3 games?

A. x + 3y/(n + 3)

B. x + y/(n + 3)

C. (x + 3y)/(n + 3)

D. (nx + 3y)/(n + 3)

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 + 3 games = \(\frac{(nx + 3y)}{( n + 3)}\)

Hence, correct answer will be (D)
