Questions correct are 130 * 0.92 or 120.

40 questions

x/30 = 0.93 x = 28 questions

x/30 = .87 x = 26 questions

0.70 x 125 = 88 questions right You can miss 125-88 = 37 questions to get 70 percent But you got to get all the rest correct!

Providing that all the other questions are correct then it is 9 questions

138 correct answers. 138/150=92

Getting 72 per cent right means if you had 100 questions you would have got 72 correct. Since there were half as many questions (50), you would have got half as many (36) correct.

You can get 60 questions wrong, which leaves you with 140 answers correct, giving you 70%.

60 percent = 60/100 60% of 40 = 60/100 x 40 = 24. Ans: 24 questions.

If there are 85 questions, a passing grade of 80% would be 68 correct answers.

22 of them for a 75% pass rate providing that the remaining 66 questions are all correct

16/20 each question is 5% so 4 wrong and 16 correct.

Assuming that you get all your answers correct (can you rely on that?), you can miss 12.

Provided that all 150 exam questions are weighted equally, then 105 correct responses is 70%.

If you got 16 questions correct on a test, and got 80 percent, then there are a total of 16 / (80/100) = 16/0.8 = 20 questions on the test.

73 questions on the test, all worth the same credit. Score 79% means you got -- 58 correct (79.452%) -- 15 wrong (20.548%)

80%=80/100 80/100 x 50 questions = 40 correct answers. therefore 50 - 40 = 10 incorrect answers.

You can answer as many as you want. But they have to be correct.

90% of 27 = 27*90/100 = 24.3 So you MUST answer 25 questions - ie all but 2 - AND get them all correct!

You can lose 44% which is 150*44/100 = 66. But then you must get every one correct!

There are many different questions you can ask about music. You can ask what instruments are playing or what genre of music you hear for example.

Multiply the total questions by the percentage (divide the percentage by 100 first) to get the number you had correct. In this case it would be 150 times (64/100) to give you 96 correct answers.

If all questions are weighted the same, then you could miss 17 questions, or 26/43 correct, and get a 60 % assuming that there are no penalties for wrong answers.
