  • Question
  • 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 ?


  • Options
  • A. 76
  • B. 79
  • C. 85
  • D. 87

  • 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
