I need sql query

Question

Hi yaar,

    I am doing project in Asp.net using c# codings.

My backend is ms sqlserver

I stored 100 questions in my database table.

From 1 to 20 questions my subtopic name is introduction
21 to 40 questions subtopic name is loop
41 to 60 questions my subtopic name is functions
61 to 80 questions  my subtopic name is pointers 
81 to 100 questions  my subtopic name is structures and unions

My question is...?

I want to display those subtopics name in the same order like (introduction, loop , functions ,pointers, structures and unions)

what is the sql query to order the subtopic in the same order by using my question number.
