  • Question
  • A batsman makes a score of 87 runs in the 17th inning and thus increases his average by 3. Find his average after 17th inning?


  • Options
  • A. 40
  • B. 39
  • C. 50
  • D. 55

  • Correct Answer
  • 39 

    Explanation
    Let the average after 17th innings = x
    Then average after 16th innings = (x - 3)
    Therefore 16 × (x - 3) + 87 = 17x
    Therefore x = 39
