Consider the following tributaries of river Ganga : 1. Gandak 2. Kosi 3. Ghaghara 4. Gomti Which one of the following is the correct order of the above rivers from east to west?
- A.3-4-1-2
- B.2-1-3-4
- C.2-3-1-4
- D.1-2-4-3
Correct answer
Explanation
The correct answer is B, 2-1-3-4. Going from east to west, the order is Kosi, Gandak, Ghaghara and Gomti.
All four join the Ganga from the north. The Kosi rises in Nepal and Tibet and joins the Ganga near Kursela in Bihar; its frequent course changes earned it the name 'Sorrow of Bihar'. West of it, the Gandak, the Narayani of Nepal, meets the Ganga at Hajipur opposite Patna. Further west the Ghaghara, which begins as the Karnali in Tibet and Nepal, joins near Chhapra. The Gomti is the westernmost of these; it rises in Pilibhit district of Uttar Pradesh, flows past Lucknow and Jaunpur, and joins the Ganga near Ghazipur.
A is wrong because it puts the Ghaghara first, though the Kosi is the easternmost. C is wrong because it places the Ghaghara east of the Gandak. D is wrong because it puts the Gandak east of the Kosi and the Gomti east of the Ghaghara.
Exam tip: Northern Ganga tributaries from west to east: Ramganga, Gomti, Ghaghara, Gandak, Kosi.
