    C 1440 Correct Answer Incorrect Answer
    D 1400 Correct Answer Incorrect Answer
    E 1380 Correct Answer Incorrect Answer

    Solution

    Let the number of matches played by player before he scores 100 be 'P'.
    Runs scored by player before he scores 100 = 32.5P
    So, (32.5P + 100) ÷ (P + 1) = 32.5 + 1.5
    => 32.5P + 100 = 34P + 34
    => 1.5P = 66
    => P = 44
    Therefore, total runs scored before he scored 100 = 32.5 × 44 = 1430
