Answer:

Hey Mate,

The question is incomplete. But don't worry i will provide you a method or trick on base of those information so you can easily solve this question.

Tenth Inning score : 100 Runs.

Suppose the average increase by 2 runs after 10 inning.

So,

Average of 10 inning = (Sum of score of all 9 innings + 100) / 10 = X + 2 Runs.

So,

9X + 100 = 10X + 20

X = 80

So, The Average of 9 innings is 80 Runs.

and The  Average of 10 innings is X + 2 = 80 + 2 = 82 Runs.
