3 runs once (one game)
6 runs twice (two game)
9 runs three times (three games)

SO we have (3*1 + 6*2 + 9*3)/6 = 42/6 = 7.

ANS: B.

Average number of runs per game = Total number of runs / Total number of games

Total number of runs = 3*1 + 6*2 + 9*3 = 42
Total number of games = 6

thus required average = 42/6 = 7. Hence B answer
