Hey dear,
I give you 3 options

• You can find all the old question papers in the official website itself. I have provided you with the link for that http://du.ac.in/du/index.php?page=academic-resources
• You can easily find the solutions of DU previous year exam papers in a any campus college photocopy shop under the name of previous year papers or last ten year papers.
• You may also purchase the solved paper booklet from any college-level bookstore under the same name. They cost around 100-150 for nearly all the available popular courses.

You can refer to various Google sites which provides DU entrance papers.
Try for Google search.
Also once see the DU official site, try to look out there
You may get it there.
Otherwise you will definitely get it on Google search.
