    Answer: 20

    Step-by-step explanation:

    Total worth of test = 50

    Percentage of test score to be gotten = 40%

    Then , the total point the student need to get to get 40% will be:

    = x/50 = 40%

    x/50 = 40/100

    x/50 = 0.4

    Cross multiply

    x = 50 × 0.4

    x = 20

    The student needs to score 20 points
