5
If u get 1-5 wrong A 5-10 wrong B 10-15 wrong C 15-20 wrong D 20 and up u get a F
The question is, "What is 30% of 40?"is/of=%/100P/40=30/100100P=1200P=12You can miss 12 and get a 70% of the test.
Oh, dude, if 80 percent of the questions were answered correctly, that means 20 percent were wrong. So, if 5 questions were missed, that's 20 percent of the total questions. To find out how many questions were answered correctly, you just need to calculate 80 percent of the total questions. Math, man, it's like magic but with numbers.
A test score of "90" represents the percentage of correct questions. Multiply this percentage by the total number of questions and you will have the number of questions correctly answered. Subtract this from the total to find answers wrong. 90% of 40 questions = .90 x 40 = 36 questions right. 40-36 = 4 answers wrong.
30 - 5 = 25 correct answers. 25/30 x 100 = 83% (rounded to a whole number)
87 and 30 is 117 wrong.
If five people answer eight questions each, then there are 40 total questions. 5 x 8 = 40 If 12 of those 40 answers are wrong, then 30% of the questions are wrong. This leaves 70% of the questions to be right. 12 / 40 = 0.3 0.3 = 30% 40 - 12 = 28 28 / 40 = 0.7 0.7 = 70%
x/30 = 1-0.87= .13 x = 30 x .13 = 4 questions wrong 26 question right = 26/30 =.87 = 87% right
You can get 5 out of 50 questions wrong to get 90%.
45.4545.. % wrong.
30
(2/30)*100 =6.666666666666667% wrong
70%
You can get at most 22 questions wrong, otherwise you will score less than 70 %. To get 70% right you can get 100 % - 70 % = 30 % wrong 30% of 75 = 30/100 x 75 = 22.5 I assume you can't get 1/2 a question wrong, so you can get at most 22 questions wrong otherwise you will score less than 70 %.
4% wrong
10/40 wrong means 30/40 correct 30/40 = 75% correct
