The average of runs of a cricket player of 10 innings was 32. How many runs must he make in his next innings so as to increase his average of runs by 4?
Solution
Correct Answer: Option D
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
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
