Question

For 8 innings, a cricketer has an average of 68 runs. In the ninth inning, he scores 220 runs. His average score increased by (rounded off to the nearest whole number):

• A. 85
• B. 23
• C. 61
• D. 17

Answer 1

Answer:

D. 17

Average after 8 innings = 68
So, total runs in 8 innings = (8 \times 68 = 544)

In the 9th inning, he scores 220 runs
New total runs = (544 + 220 = 764)

New average after 9 innings = (764 \div 9 \approx 84.89)

Increase in average = (84.89 - 68 = 16.89)

Rounded to nearest whole number:

17 runs
