title: Group users by age for a range
body: <p>I have some data which i need to make some statistics. I need to group the users by age. </p>
  
  <pre><code>var byAge = displayResult.GroupBy(x =&gt; x.Age);
  </code></pre>
  
  <p>Which i can do as above. However, this gives me ages like 19, 20, 21 etc. what I want is grouping age by 10 years, such as </p>
  
  <p>users between 10-20 yearsold, 20-30 years old, 30-40 years old etc. </p>
  
  <p>How can i get that?</p>
