Question from Gregmat+ average

[image] Hi everyone, So here, Greg solved the question and explained the answer to be 17.6. But the answer cannot be 17.6 since the mean will be 16 and in the question, it is asked that the mean should be greater than 16. So the answer should be 20? Am I wrong in my justification?
