Answers.

Let the average after 17 innings = x   Total runs scored in 17 innings = 17x   Average after 16 innings = (x-3)   Total runs scored in 16 innings = 16(x-3)   Total runs scored in 16 innings + 82 = Total runs scored in 17 innings   =&gt; 16(x-3) + 82 = 17x   =&gt; 16x - 48 + 82 = 17x   =&gt; x = 34   Answer is 34.
