    Answer:

    31 questions, but it’s impossible to score 75%.

    Step-by-step explanation:

    It’s impossible to get exactly a score of 75% out of 42 questions. However, you can get the next closest percentage, which is rounded up to 74% with 31 questions right out of 75.

    This is because 31 / 42 = 0.738… You can round 0.738 to 0.74. Then multiply 0.74 by 100, which gives you 74. This means the closest score you can get to 75 is 74% with 31 questions.

    You can also score 76% with 32 questions right out of 42 questions. This is because 32 / 42 = 0.761… You can round 0.761 to 0.76. Then multiply 0.76 by 100, which gives you 76.
