- A cricketer has a mean score of 58 runs in nine innings.
Question 1:
A cricketer has a mean score of 58 runs in nine innings. Find out how many runs are to be scored by him in the tenth innings to raise the mean score to 61. A. 77
B. 67
C. 88
Feedback Mean score of 9 innings = 58 runs.
Total score of 9 innings = (58 x 9) runs = 522 runs
A required mean score of 10 innings = 61 runs.
Required total score of 10 innings = (61 x 10) runs = 610 runs.
Number of runs to be scored in the 10th innings
= (total score of 10 innings) - (total score of 9 innings)= (610 -522) = 88.
Hence, the number of runs to be scored in the 10th innings = 88.
Total score of 9 innings = (58 x 9) runs = 522 runs
A required mean score of 10 innings = 61 runs.
Required total score of 10 innings = (61 x 10) runs = 610 runs.
Number of runs to be scored in the 10th innings
= (total score of 10 innings) - (total score of 9 innings)= (610 -522) = 88.
Hence, the number of runs to be scored in the 10th innings = 88.
