Q. Consider the following rivers:

1. Kaveri
2. Vaigai
3. Tampraparni
4. Periyar

Which of the following is the correct order of the above rivers from north to south?
Answer: 4 3 1 2

Next, the Tampraparni River flows to the south of the Kaveri River, which is situated in the central region of Tamil Nadu. Lastly, the Vaigai River flows further north compared to the Kaveri, making it the northernmost among these rivers. Thus, the correct order from north to south is Periyar (4), Tampraparni (3), Kaveri (1), and Vaigai (2). Thus, the correct order is 4 3 1 2.
