Although five of John's answers were incorrect, 90% of his answers were correct. How many questions did John answer in all?

fiasKO [112]

Answer:

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

$0.1n = 5$

$n = \frac{5}{0.1}$

$n = 50$

John answered 50 questions.
