Which of the following rivers is NOT a tributary of the Yamuna?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Gandak
The Chambal, Betwa and Ken rise on the peninsular plateau and flow north to join the Yamuna. The Gandak rises in the Nepal Himalaya and joins the Ganga near Patna in Bihar, so it is not a tributary of the Yamuna.
