Q. Consider the following:

1. Magadha
2. Kosala
3. Vatsa
4. Avanti

Which of the following is the correct order of the above from east to west?
Answer: 4 3 2 1
Notes: Magadha, Kosala, Vatsa, and Avanti were important kingdoms in ancient India. Avanti was located in the western part of the region, while Vatsa was situated to the east of Avanti, in what is now Uttar Pradesh. Kosala, ruled by Prasenajit, was further east of Vatsa, while Magadha, known for its powerful Haryanka dynasty, was located to the east of Kosala. Thus, the correct order from east to west is Avanti (4), Vatsa (3), Kosala (2), and Magadha (1). Thus, the correct order is 4 3 2 1.
