  • Question
  • The average score of a cricketer for 10 matches is 43.9 runs. If the average for the first six matches is 53 , the average for the last four matches is?


  • Options
  • A. 17.15
  • B. 29.75
  • C. 30.25
  • D. 31

  • Correct Answer
  • 30.25 

    Explanation

    Let the average for last 4 matches be y.
    Sum of score for 10 matches = sum of score for first 6 matches + sum of score of last 4 matches.
    So 53 x 6 + 4y = 10 x 43.9
    ? 4x= 439-318
    ?4x= 121
    ? x= 30.25
