    There is 25 questions on her test

    That is because for Josephine every 40% means that she got 10 questions right

    40% = 10

    40% = 10

    20% = 10/2 or 5

    I would divide 10 by 2 because 20 is half of 40 and you'll get 5

    Add all the questions and you'll get

    10 + 10 + 5 = 25 questions
