Not exactly. If you don't have the same number of answers that the number of questions, so your counter is not properly set. See that:

  What is the value of $100/10$?

If you comment one solution, then, you get "Answer to question 1", instead of "Answer of question 2", which is really. No always a question has an answer provided by me ;-)
You can add a answer block which increments the answer counter.
\defineblock[question]
\defineblock[answer]
\defineenumeration[question][text={Question}]
\defineenumeration[answer]  [text={Answer}]
\keepblocks[question]
\hideblocks[answer]

\chapter{Question}

  \stopanswer
\endanswer
\beginquestion
  \startquestion
      Question 2.
  \stopquestion
\endquestion
\beginanswer
  \incrementcounter[answer]
\endanswer
\beginquestion
