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 ?

Correct Answer: 76

Explanation:

Average = total runs / no.of innings = 32 


So, total = Average x no.of innings = 32 x 10 = 320.


 


Now increase in avg = 4runs. So, new avg = 32+4 = 36runs 


Total runs = new avg x new no. of innings = 36 x 11 = 396 


Runs made in the 11th inning = 396 - 320 = 76
