Average

``````x + 3 = ( (16 * x ) + 87 ) / 17
``````

Solving above x = 36

The average after 17th innings is x + 3 = 39

What is 82 here?
not 82 it is 87 now i edited, thanks for noted.

Let X be the average after 16th innings
Then we can write the following equation:
(X x 16 + 87) / 17 = X + 3 ; X = 36
Then the average after the 17th winning is 36 + 3 = 39
