Purna river is a tributary of which of the following rivers?

Question

UnlockIAS · Accepted Answer

Correct — B, Tapti. The Purna River rises in the eastern Satpura Range in Betul district, Madhya Pradesh, flows west through Maharashtra's Vidarbha region (Amravati, Akola, Buldhana, Jalgaon), and joins the Tapti (Tapi) as its major left-bank tributary at Changdev in Jalgaon district.

Why the other options are wrong — (a) The Narmada is MP's other major west-flowing river, but the Purna does not feed it — it flows into the parallel Tapti system instead.  (c) Sonar is itself a small MP river (a Betwa tributary in the Yamuna system) — it is not the river the Purna joins.  (d) Dhasan is a Betwa/Yamuna-system tributary in northern MP — unrelated to the Purna-Tapti system further south.

Concept: The Purna is the Tapti's most significant tributary — rising in the eastern Satpura Range of Betul district, MP, it drains a large part of the Vidarbha region of Maharashtra before rejoining the Tapti. A different, same-named Purna River elsewhere in Maharashtra is a Godavari tributary — the name clash is a classic exam trap, so always fix the source state/course before answering.
