  1. Out of 100 questions,
    48 correct answers
    11 blank
    41 wrong answers
    total 100

    We don't get to see the scheme.
    Assume the scheme says:
    1 point for each correct answer,
    -1 point for each incorrect answer,
    0 for leaving it blank.
    So total points
    =48-41-0
    =7
