Once I had been to the post-office to buy stamps of five rupees, two rupees and one rupee. I paid the clerk Rs $20$, and since he did not have change, he gave me three more stamps of one rupee. If the number of stamps of each type that I had ordered initially was more than one, what was the total number of stamps that I bought?
1. $10$
2. $9$
3. $12$
4. $8$
