1. The average of runs of a cricket player of 10 innings was 32. How many runs must he make in his next inning so as to increase his average of runs by 4?
- A. 2
- B. 2
- C. 2
- D. 2
Answer: Option D
Explanation:
Average= Total runs/ No. of innings =32
So,
Total runs
=32×10
=320
Now increase in average is 4 runs
so,
New average =32+4=36 runs
Total runs =36×11=396
Runs made in the 11th inning =396−320=76
So,
Total runs
=32×10
=320
Now increase in average is 4 runs
so,
New average =32+4=36 runs
Total runs =36×11=396
Runs made in the 11th inning =396−320=76
