Greetings Naveed!

Hope you're doing great.

Congrats on completing your graduation degree! Just for a fact, only 5% of the total youth population in our country complete their graduation every year. Since you want to pursue further education and that too in the field of Geography/Political Science. I assume you're preparing for civil service examination. Having said that most no. of people opt to study MA subjects for either Civil service preparation or for PhD. 

If you're following the official notification from JNU then you must be knowing that the application form for Master's program is now available. For more details regarding the same, you can visit this website: https://university.careers360.com/articles/jnu-application-form

Now, coming back to your question you're looking forward to previous years sample papers, the same you can find at the official site of JNU or you can look out for the same in Quora. I'd recommend going through the last five years question papers will be enough for preparation. Best wishes!

Here is the link where you can find the previous year papers: http://jnueeqp.com/jnu-entrance-exam-previous-years-question-papers/
