69
100 - 69 = 31, and it's percent, so it's .31 .31*30 = 9.3, but you must round down or up (down to get more than 69%), so you can miss 9 questions and still fail.
Short answer: 0.69Take 100. 31% = 31, 100-31=69Of course, when you increase the result by 31 percent you do not get the 100 back. But that was not the question.But, for completeness what do I multiply by to get the number, when adding 31 percent, gives me the original number, it is 0.7633 (1/1.31)
31 + 69 = 100

quite a simple one, the trick is to work out what 1% of 240 is then multiply it by 31 (100-69=31). taking away 69% from a number is the same as working out the difference, in this case 31% so, 240/100=2.4, and 31x2.4=74.4 you could also work out 69% and minus the answer from 240, 2.4x69=165.6, 240-165.6=74.4
50% of 69 = 50% * 69 = 0.5 * 69 = 34.5
