John answered 50 questions.
Step-by-step explanation:
Although five of John's answers were incorrect, 90% of his answers were correct.
This means that 5 is 100 - 90% = 10% of the total number of questions, n. So
![0.1n = 5](https://tex.z-dn.net/?f=0.1n%20%3D%205)
![n = \frac{5}{0.1}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B5%7D%7B0.1%7D)
![n = 50](https://tex.z-dn.net/?f=n%20%3D%2050)
