  1. 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 ?
    1. 17.15
    2. 29.75
    3. 30.25
    4. 31
  1. Correct Option: C

    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
