1.  A cricketer has a certain average for 10 innings. In the eleventh inning, he scored 108 runs, thereby increasing his average by 6 runs. His new average is :
A. 48 runs
B. 52 runs
C. 55 runs
D. 60 runs

Answer: Option A

Explanation:

Let average for 10 innings be x.

Then, 10x + 108 = x + 6
11


 11x + 66 = 10x + 108

 x = 42

New average = (x + 6) = 48 runs.
