Question

Which of the following rivers flows from Central India and joins river Ganga?

a. Betwa

b. Kosi

c. Gomti

d. Ghaghra

e. None

Answer 1

Hint: Ganga is said to be the longest river of India and the Ganga river system spreads into a number of states such as Uttar Pradesh, Madhya Pradesh, Rajasthan, Bihar, West Bengal, Uttarakhand, Jharkhand, Haryana, Chhattisgarh, Himachal Pradesh and Union Territory of Delhi.

Complete solution:

Let's look at the options one by one:

Option a: Betwa river rises from the Vindhya ranges in Madhya Pradesh; thus it flows in central India but it doesn't directly join the Ganga. It is a tributary of Yamuna river that joins the Ganga. Thus, this option is incorrect. 

Option b: Kosi is also one of the important as well as largest tributaries of Ganga that runs from Nepal to India to join Ganga. As it is a left bank tributary, it does not run in central India, thus this option is also incorrect.

Option c: Gomati is also said to be a left bank tributary of Ganga that joins it in Uttar Pradesh in Ghazipur. Thus, this option is also incorrect.

Option d: Ghaghra is a trans boundary river that starts from the Tibetan plateau near the Mansarovar lake. It is one of the major left bank tributaries of Ganga that joins it in Bihar. Thus, it is also an incorrect option

Option e: As all the above given options are incorrect, therefore the correct answer here is Option e. None of the options given above satisfy the statement that deals with the river that flows in Central India and joins the Ganga river. 

Therefore, the correct answer is Option (e).

Note: In order to deal with questions related to rivers, you must know the tributaries of the particular river and do take care of the left and right bank tributaries. In order to learn them you should go through the individual maps of the river system and try to draw it in your notebook.
