Q. Consider the following:

1. Shigar
2. Gasting
3. Khurram
4. Rind
5. Tochi
6. Viboa

Which of the above are the tributaries of the Indus river system?
Answer: Only 1, 2, 3, 5, and 6
Notes: The Indus receives a number of Himalayan tributaries such as the Shyok, the Gilgit, the Zaskar, the Hunza, the Nubra, the Shigar, the Gasting and the Dras. It finally emerges out of the hills near Attock where it receives the Kabul river on its right bank. The other important tributaries joining the right bank of the Indus are the Khurram, the Tochi, the Gomal, the Viboa and the Sangar. They all originate in the Sulaiman ranges.
