Answer Explanation
Since, We have given average score of first seven innings = 51.72
Therefore, Total score of first seven innings = 51.72 x 7
= 362.04
Now, Average score of a batsman in eight innings = 58.62 (given)
Now, the eighth inning be x , then we get
( 51.72 x 7 + x ) / 8 = 58.62
362.04 + x = 58.62 x 8
362.04 + x = 468.96
x = 106.92 Hence, his score in the eighth inning was 106.92.
