Question

Which of the following is not a tributary of the Sindhu river?
a)Chenab
b)Satluj
c)Betwa
d)Ravi

Answer 1

Hint: The Sindhu river or the Indus river rises in Tibetan Plateau and joins the Arabian Sea. It is one of the major rivers of the Indo-Gangetic plain

Complete answer: The Sindhu river has a number of tributaries like Shyok, the Gilgit, the Zaskar, the Hunza, the Nubra, the Shigar, and the Dras.
Let us look a the options given to us:
Option (A)Chenab originates in Lahaul and Spiti region and joins Jhelum , which is a tributary of Indus, at Trimmu. Hence Chenab is a tributary of Indus.
Option (B) Satluj originates in Tibetan Plateau and it joins the Beas river before joining the Chenab river at Bahawalpur. This combination of rivers finally join the Indus.
Option (C )Betwa river is a tributary of Yamuna. It rises in Vindhyan range and flows through the Malwa plateau. Betwa is thus a Peninsular river
Option (D ) Ravi river rises in Kangra region of Himachal Pradesh and meets Chenab near Ahmadpur Sial. Chenab finally joins Indus and hence Ravi is also a tributary of Indus.

Therefore the correct answer is option (C) Betwa.

Note: River Indus and its tributaries are transboundary rivers and flow both in India and Pakistan. Therefore ,under the Indus Water Treaty of 1960 , control of Beas, Ravi and Sutlej was given to India. Indus, Jhelum and Chenab were put under Pakistan’s authority.
