Averages

by naaga » Tue Feb 24, 2009 1:13 am
. After 5 games, a rugby team had an average of 28 points per game. In order to increase the average by n points, how many points must be scored in a 6th game?
(A) n
(B) 6n
(C) 28n
(D) 28 + n
(E) 28 + 6n

can anyone explain a simple method to solve this averages problem.

Thanks in advance.

If he scores 28 points in the 6th game the average will remain 28. Since we need an increase of n in the average over 6 games he needs to score 6n points more. Hence he should score 28+6n

Anyway, please search the forum before posting. This query is already answered here.
