Answer:

4 problems

Step-by-step explanation:

solution

100%_84%=16%

equate 100%=25 questions

therefore 16%=?

16%÷100%×25=4

=4

Step-by-step explanation:

Total questions = 25

In 100% Maria got 84% correct

percentage that she got wrong = 100% - 84%

= 16%

Now

Problems that she got wrong = 16% of 25

= 16/100 * 25

= 0.16 *25

= 4

Therefore she got 4 questions wrong.
