Answer:

8 students

Step-by-step explanation:

You know that 11 people passed the test, so 10 people did not pass the test. 4 people didn't do their homework and didn't pass the test which means 6 people did the homework but did not pass the test. We also know that 14 students did their homework meaning that 14-6= 8 students did their homework and passed the test.
